Check Digit Verification of cas no

The CAS Registry Mumber 193738-04-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,7,3 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 193738-04:
(8*1)+(7*9)+(6*3)+(5*7)+(4*3)+(3*8)+(2*0)+(1*4)=164
164 % 10 = 4
So 193738-04-4 is a valid CAS Registry Number.

Photochemical synthesis of s-triazolo[3,4-b]benzothiazole and mechanistic studies on benzothiazole formation

Jayanthi,Muthusamy,Paramasivam,Ramakrishnan,Ramasamy,Ramamurthy

, p. 5766 - 5770 (2007/10/03)

A general photochemical synthesis of s-triazolo[3,4-b]benzothizoles from 4,5-disubstituted 1,2,4-triazole-3-thione is described. Steady photolysis, quantum yield determination, and laser flash photolysis experiments have been carried out. An intermolecular electron transfer mechanism has been proposed.
