Check Digit Verification of cas no

The CAS Registry Mumber 1304780-03-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,4,7,8 and 0 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1304780-03:
(9*1)+(8*3)+(7*0)+(6*4)+(5*7)+(4*8)+(3*0)+(2*0)+(1*3)=127
127 % 10 = 7
So 1304780-03-7 is a valid CAS Registry Number.

Syntheses of 2-deoxy-2,3-didehydro-N-acetylneuraminic acid analogues modified by N-sulfonylamidino groups at the C-4 position and biological evaluation as inhibitors of human parainfluenza virus type 1

, p. 2418 - 2427 (2011/05/12)

Eleven novel sialidase inhibitors 9 and 10 with an N-sulfonylamidino group at the C-4 position of Neu5Ac2en 1 against human parainfluenza virus type 1 (hPIV-1) were synthesized using copper-catalyzed three-component coupling reactions, and their inhibitory activities against hPIV-1 sialidase were studied.
