Check Digit Verification of cas no

The CAS Registry Mumber 100928-04-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,9,2 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 100928-04:
(8*1)+(7*0)+(6*0)+(5*9)+(4*2)+(3*8)+(2*0)+(1*4)=89
89 % 10 = 9
So 100928-04-9 is a valid CAS Registry Number.

Synthesis and biological evaluation of calcioic acid

Arnold, Leggy A.,Di Milo, Elliot S.,Mutchie, Tania R.,Yu, Olivia B.

, (2020)

Herein, we describe the synthesis of calcioic acid following a recently developed synthetic strategy for calcitroic acid. Several improvements to reaction conditions were made, which resulted in higher yields. The improved workup and isolation procedures

Efficient and scalable total synthesis of calcitroic acid and its 13C-labeled derivative

Meyer, Daniel,Rentsch, Lara,Marti, Roger

, p. 32327 - 32334 (2014/08/18)

Calcitroic acid, the deactivated form of the physiological active vitamin D3 metabolite calcitrol, and its 13C labeled derivative has been synthesized starting from the commercially available Inhoffen-Lythgoe diol in 11 steps with an

Synthesis and preliminary biological evaluation of 20-epi-eldecalcitol [20-epi-1α,25-dihydroxy-2β-(3-hydroxypropoxy)vitamin D3: 20-epi-ED-71]

scheme or table, p. 25 - 28 (2011/12/01)

Eldecalcitol [1α,25-dihydroxy-2β-(3-hydroxypropoxy)vitamin D3, developing code: ED-71] is an analog of active vitamin D3, 1α,25-dihydroxyvitamin D3 [1,25(OH)2D3] that possesses a hydroxypropoxy substituent at the 2β-position of 1,25(OH)2D3. Eldecalcitol has potent biological effects on bone and is now in preparation for approval as a promising medicine for the treatment of osteoporosis in Japan. To explore chemical structure-biological activity relationships between eldecalcitol and related analogs, we have already synthesized 1-epi-eldecalcitol, 3-epi-eldecalcitol, and 1,3-diepi-eldecalcitol with inherent biological interests of each targeted analog and evaluated their biological responses. It has been reported that 20-epi-1,25(OH)2D3, a diastereomer of 1,25(OH)2D3 that possesses an inverted methyl substituent at the 20-position of the side chain, shows remarkably enhanced biological activities compared to parental compound, 1,25(OH)2D3. As a continuation of our modification studies on eldecalcitol, we took great interest in 20-epi-eldecalcitol and its biological responses. In this paper, the synthesis of 20-epi-eldecalcitol by the Trost coupling reaction between the A-ring fragment and the C/D-ring fragment as well as in vitro preliminary biological evaluation of 20-epi-eldecalcitol are described. In the induction of human myeloid leukemia cell (HL-60) differentiation, inhibition of the human histiocytic lymphoma cell (U937) proliferation, and increase in osteocalcin concentration in the human osteosarcoma cell (MG-63), 20-epi-eldecalcitol showed significantly enhanced activity compared to eldecalcitol.
