144923-61-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144923-61-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,9,2 and 3 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 144923-61:
(8*1)+(7*4)+(6*4)+(5*9)+(4*2)+(3*3)+(2*6)+(1*1)=135
135 % 10 = 5
So 144923-61-5 is a valid CAS Registry Number.

Synthetic O-glycopeptides as model substrates for glycosyltransferases
Schultz,Kunz
, p. 1205 - 1220 (2007/10/02)
A new approach to O-glycopeptides of the glucosamine type is described. N-Urethane protected, peracetylated glucosamine is converted into its 1-thio (1-bromo) derivative and used for glycosylation of a variety of protected serine or threonine derivatives
