Check Digit Verification of cas no

The CAS Registry Mumber 404391-02-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,4,3,9 and 1 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 404391-02:
(8*4)+(7*0)+(6*4)+(5*3)+(4*9)+(3*1)+(2*0)+(1*2)=112
112 % 10 = 2
So 404391-02-2 is a valid CAS Registry Number.

Dialkylphosphates as stereodirecting protecting groups in oligosaccharide synthesis

Yamada, Takeshi,Takemura, Kazunobu,Yoshida, Jun-Ichi,Yamago, Shigeru

, p. 7575 - 7578 (2008/02/01)

(Chemical Equation Presented) Double duty: A phosphoric ester at the C2 position in glycosyl donors directs the glycosylation to occur selectively at the anomeric carbon atom with complete 1,2-trans selectivity. Since the phosphoric ester can be removed to give the hydroxy function, this group serves as a stereodirecting protecting group in oligosaccharide synthesis.
