Check Digit Verification of cas no
The CAS Registry Mumber 733047-53-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,3,3,0,4 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 733047-53:
(8*7)+(7*3)+(6*3)+(5*0)+(4*4)+(3*7)+(2*5)+(1*3)=145
145 % 10 = 5
So 733047-53-5 is a valid CAS Registry Number.

Synthesis of novel analogues of 1α,25-dihydroxyvitamin D3 with side chains at C-18
Moman, Edelmiro,Nicoletti, Daniel,Mourino, Antonio
, p. 4615 - 4625 (2007/10/03)
Novel analogues of the hormone 1α,25-(OH)2-D3 with side chains attached to C-18 were synthesized by a versatile route in which key steps were the remote radical-induced functionalization of the 18-methyl by the C-8β-hydroxyl group an
