Check Digit Verification of cas no
The CAS Registry Mumber 86-60-2 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 6 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 86-60:
(4*8)+(3*6)+(2*6)+(1*0)=62
62 % 10 = 2
So 86-60-2 is a valid CAS Registry Number.

Solid phase acylation of aminosulfonic acids
-
, (2008/06/13)
This invention is directed to the acylation of aminosulfonic acids in the solid phase. Two discrete, sequential chemical reactions occur, i.e. (1) the neutralization of the aminosulfonic acid, and (2) the subsequent amine acylation, to produce an improved neutralized acyl-aminosulfonic acid at a reduced cost. Aminosulfonic acids having the general formula HO3 S-A-NH2 are acylated to neutralized acyl-aminosulfonic acids having the general formula RCONH-A-SO3 M, where A is an unsubstituted or substituted aliphatic, aromatic or heteroaromatic group and M is a neutralizing agent moiety. The yield is virtually quantitative.
