93748-46-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 93748-46-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,7,4 and 8 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 93748-46:
(7*9)+(6*3)+(5*7)+(4*4)+(3*8)+(2*4)+(1*6)=170
170 % 10 = 0
So 93748-46-0 is a valid CAS Registry Number.

Yamada, Sachiko,Shiraishi, Masami,Ohmori, Masayuki,Takayama, Hiroaki
, p. 3347 - 3350 (2007/10/02)
25-Hydroxyvitamin D2 was synthesized conveniently and stereoselectively for the first time by utilizing Sharpless' chiral epoxidation and the subsequent regio- and stereoselective methylation with lithium dimethylcuprate to introduce the desire
