91083-81-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91083-81-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,0,8 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 91083-81:
(7*9)+(6*1)+(5*0)+(4*8)+(3*3)+(2*8)+(1*1)=127
127 % 10 = 7
So 91083-81-7 is a valid CAS Registry Number.

On the reaction of α-chlorocarbenium ions with sulfinylamines
Voges,Hamed,El-Badry,Ismail,Jochims
, p. 253 - 260 (2007/10/02)
Aryl-, and vinyltrichloromethanes 1 are transformed with antimony pentachloride to α,α-dichlorocarbenium salts 2, which react with sulfinylamines 3 to afford nitrilium salts 4 in good yields. In contrast to this preparatively useful reaction, the reaction
