Check Digit Verification of cas no

The CAS Registry Mumber 139268-13-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,2,6 and 8 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 139268-13:
(8*1)+(7*3)+(6*9)+(5*2)+(4*6)+(3*8)+(2*1)+(1*3)=146
146 % 10 = 6
So 139268-13-6 is a valid CAS Registry Number.

Mass Spectral Fragmentation Patterns of Some Substituted 1,2,4-Triazoles and 1,2,4-Triazolo[3,4-b]1,3,4-thiadiazoles ψ

Holla, B. Shivarama,Shivananda,Akberali

, p. 532 - 533 (2007/10/03)

Several substituted 1,2,4-triazoles (1) have been synthesized and converted into 1,2,4-triazolo[3,4-b]1,3,4-thiadiazoles (3). They have been characterized by ir, nmr and mass spectral studies. The mass spectral fragmentation patterns of the compounds are
