Check Digit Verification of cas no

The CAS Registry Mumber 916225-63-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,6,2,2 and 5 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 916225-63:
(8*9)+(7*1)+(6*6)+(5*2)+(4*2)+(3*5)+(2*6)+(1*3)=163
163 % 10 = 3
So 916225-63-3 is a valid CAS Registry Number.

Efficient synthesis of an α(2,9) trisialic acid by one-pot glycosylation and polymer-assisted deprotection

Tanaka, Hiroshi,Tateno, Yusuke,Nishiura, Yuji,Takahashi, Takashi

supporting information; experimental part, p. 5597 - 5600 (2009/06/23)

(Chemical Equation Presented) An efficient synthesis of α(2,9) trisialic acid has been achieved via one-pot glycosylation and polymer-assisted deprotection. The synthesis involves chemo- and regioselective α-sialylation of ethylthiosialoside with the S-be
