Check Digit Verification of cas no

The CAS Registry Mumber 1240038-39-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,0,3 and 8 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1240038-39:
(9*1)+(8*2)+(7*4)+(6*0)+(5*0)+(4*3)+(3*8)+(2*3)+(1*9)=104
104 % 10 = 4
So 1240038-39-4 is a valid CAS Registry Number.

Thio analogues of pyrimidine bases: Syntheses and spectral study of new potentially biologically active 2,4-di-ortho-(meta- and para-)bromo- (chloro and nitro)-benzylthio-5-bromouracils (and 6-methyluracils)

Bartkowiak, Grazyna,Wyrzykiewicz, Elzbieta,Schroeder, Grzegorz,Walkowiak, Anna,Szponar, Anna,Pawlak, Ilona

, p. 1429 - 1436 (2010)

Eighteen new 2,4-di-ortho- (meta- and para-) bromo-(chloro- and nitro-)benzylthio-5-bromouracils (and 6-methyluracils) have been prepared. The structures of these compounds were confirmed by spectral (IR, UV/vis, 1H NMR) and elemental analyses. Estimation
