Check Digit Verification of cas no

The CAS Registry Mumber 1059650-01-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,9,6,5 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1059650-01:
(9*1)+(8*0)+(7*5)+(6*9)+(5*6)+(4*5)+(3*0)+(2*0)+(1*1)=149
149 % 10 = 9
So 1059650-01-9 is a valid CAS Registry Number.

An improved synthesis of methyl protodioscin: Tautomerization and direct access to the 3-o-substituted kryptogenin

Xu, Qing-Chun,Liu, Yang,Liu, Jiao,He, Chun-Xian,Yan, Mao-Cai,Cheng, Mao-Sheng

, p. 780 - 781 (2008/12/21)

The acid-catalyzed tautomerization of 3-O-substituted kryptogenin 2 was studied, and the effects of acids such as silica gel, TMSOTf, acetic acid, and CDCl3, are discussed. Additionally, a Zn/KI/HOAc reduction based on this tautomerization was adopted, which afforded 2 directly, and provided a facile procedure for the synthesis of methyl protodioscin and other furostanol saponins in a mild way.
