31789-69-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 31789-69-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,7,8 and 9 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 31789-69:
(7*3)+(6*1)+(5*7)+(4*8)+(3*9)+(2*6)+(1*9)=142
142 % 10 = 2
So 31789-69-2 is a valid CAS Registry Number.

Zelenskaya,Kozinskii,Nazarenko,Ranskii
, p. 1071 - 1072 (2007/10/02)
The authors found in the course of development of methods for synthesis of 5-amino-1,2,3-thiadiazoles that the reaction of tosyl azide with thioacetamide (Ia) and with thioacetanilide (Ib) proceeds at the C equals S bond with formation of N-tosylacetamidi
