Check Digit Verification of cas no

The CAS Registry Mumber 1268673-31-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,8,6,7 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1268673-31:
(9*1)+(8*2)+(7*6)+(6*8)+(5*6)+(4*7)+(3*3)+(2*3)+(1*1)=189
189 % 10 = 9
So 1268673-31-9 is a valid CAS Registry Number.

Facile synthesis of four natural triterpene saponins with important antitumor activity

Guo, Tiantian,Liu, Qingchao,Zhang, Lei,Wang, Peng,Li, Yingxia

, p. 357 - 371 (2011)

The first synthesis of four natural triterpene saponins, which exhibit significant antitumor activities, was concisely achieved by adopting a stepwise glycosylation. The key intermediate 13 was afforded via Bu2SnO-mediated regioseletive benzoylation. Duri
