Check Digit Verification of cas no

The CAS Registry Mumber 1235555-40-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,5,5,5 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1235555-40:
(9*1)+(8*2)+(7*3)+(6*5)+(5*5)+(4*5)+(3*5)+(2*4)+(1*0)=144
144 % 10 = 4
So 1235555-40-4 is a valid CAS Registry Number.

5- N,4- O -carbonyl-7,8,9-tri- O -chloroacetyl-protected sialyl donor for the stereoselective synthesis of α-(2→9)-tetrasialic acid

Lin, Chang-Ching,Lin, Nai-Pin,Sahabuddin, L. Sk,Reddy, Vijaya Raghava,Huang, Li-De,Hwang, Kuo Chu,Lin, Chun-Cheng

experimental part, p. 4921 - 4928 (2010/10/21)

(Figure presented) An efficient stereoselective synthesis of α-(2→9)-tetrasialic acid was achieved using tri-O-chloroacetyl- derivatized sialyl donor and a triol sialyl acceptor. Both the acceptor and the donor were also protected with a cyclic 5-N-4-O-carbonyl protecting group. The donor is highly reactive and enabled α-selective sialylation with various primary, secondary, and tertiary acceptors under in situ activation conditions (NIS/TfOH, -78 °C, acetonitrile/dichloromethane). The trans-fused oxazolidinone ring and O-chloroacetyl protecting groups were easily removed under mild reaction conditions to provide the fully deprotected α(2→9)-tetrasialic acid.
