Check Digit Verification of cas no

The CAS Registry Mumber 194291-45-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,4,2,9 and 1 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 194291-45:
(8*1)+(7*9)+(6*4)+(5*2)+(4*9)+(3*1)+(2*4)+(1*5)=157
157 % 10 = 7
So 194291-45-7 is a valid CAS Registry Number.

Formal synthesis of tautomycin, which inhibits type 1 and type 2A protein phosphatases, was achieved. Spiroketal diol 21 was synthesized from alcohol 2 or 11. The regioselective enzymatic acetylation of 21 with the lipase 'Amano PS' gave monoacetate 23 in

Synthetic study of tautomycin. I. Synthesis and regioselective enzymatic acetylationof a spiroketal diol related to the C5-C16 fragment

Nagumo, Shinji,Arai, Takayuki,Akita, Hiroyuki

, p. 5165 - 5168 (2007/10/03)

Spiroketal diol 1 was prepared from 5, which can be obtained by enantio-selective enzymatic acetylation of meso diol 6, in 12 steps in 16.5% total yield and its regioselective protection was achieved by an enzymatic method to give 1 6 in high yield.
