Check Digit Verification of cas no

The CAS Registry Mumber 219720-80-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,7,2 and 0 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 219720-80:
(8*2)+(7*1)+(6*9)+(5*7)+(4*2)+(3*0)+(2*8)+(1*0)=136
136 % 10 = 6
So 219720-80-6 is a valid CAS Registry Number.

Synthesis of the diazepanone-nucleoside portion of liposidomycins by aldol reaction of the enolate of diazepanone with a nucleoside 5'-aldehyde

Kim, Kwan Soo,Ahn, Yeong Hee

, p. 3601 - 3605 (2007/10/03)

The diazepanone-nucleoside part of liposidomycins has been synthesized by the aldol reaction between the enolate of a stereochemically defined diazepanone and a uridine 5'-aldehyde. The configurations of two new stereocenters in the aldol product have bee
