Check Digit Verification of cas no

The CAS Registry Mumber 193953-68-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,9,5 and 3 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 193953-68:
(8*1)+(7*9)+(6*3)+(5*9)+(4*5)+(3*3)+(2*6)+(1*8)=183
183 % 10 = 3
So 193953-68-3 is a valid CAS Registry Number.

Oligosaccharide synthesis based on glycosyl donors and accepters carrying phosphorus-containing leaving groups

Hashimoto, Shun-Ichi,Sakamoto, Hiroki,Honda, Takeshi,Ikegami, Shiro

, p. 5181 - 5184 (2007/10/03)

Efficient synthetic strategy for oligosaccharides has been developed by exploiting the difference in anomeric reactivity between glycosyl donors and acceptors carrying phosphorus-containing leaving groups, wherein, the tetramethylphosphoroamidate group plays a pivotal role as anomeric protective group as well as leaving group.
