74140-95-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74140-95-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,1,4 and 0 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 74140-95:
(7*7)+(6*4)+(5*1)+(4*4)+(3*0)+(2*9)+(1*5)=117
117 % 10 = 7
So 74140-95-7 is a valid CAS Registry Number.

, p. 1394 - 1405 (2007/10/02)
Heterosubstituents such as chlorine, diphenylsulfonio, triphenylphosphonio, and triphenylarsonio are shown to migrate between the nitrogen atoms in N,N'-dimethylbenzamidine.The triphenylstibonio group, however, prefers a 4-membered chelate complex with 6
