831-21-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 831-21-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,3 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 831-21:
(5*8)+(4*3)+(3*1)+(2*2)+(1*1)=60
60 % 10 = 0
So 831-21-0 is a valid CAS Registry Number.

An efficient, one-pot synthesis of 3-alkyl or aryl sydnoneimines
Beal,Turnbull
, p. 673 - 676 (2007/10/02)
In a 'one-pot' process, a variety of 3-alkyl and 3-aryl sydnoneimine hydrochlorides can be prepared in high yield, under mild conditions, by nitrosation of the corresponding aminoacetonitrile with isoamyl nitrite in diethyl ether followed by cyclization w
