Check Digit Verification of cas no

The CAS Registry Mumber 134699-89-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,6,9 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 134699-89:
(8*1)+(7*3)+(6*4)+(5*6)+(4*9)+(3*9)+(2*8)+(1*9)=171
171 % 10 = 1
So 134699-89-1 is a valid CAS Registry Number.

8-O-Sialylation of neuraminic acid acceptor reactivity and anomeric stereocontrol

Castro-Palomino, Julio C.,Tsvetkov, Yury E.,Schneider, Regine,Schmidt, Richard R.

, p. 6837 - 6840 (2007/10/03)

2-O-unprotected and 2-deoxy-2,3-dehydro-neuraminic acid derivatives 2, 4, and 10 exhibit enhanced acceptor properties at their 8-hydroxy group in sialylation reactions with phosphite 5 as donor: yet, mainly (10) or exclusively (2, 4) β-glycoside bond formation was observed. The 3-phenylthionocarbonate group as stereodirecting auxiliary group in the sialyl donor 11 led with 10 as acceptor to exclusive formation of α(2-8)-linked disaccharide.
