Check Digit Verification of cas no

The CAS Registry Mumber 956-28-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,5 and 6 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 956-28:
(5*9)+(4*5)+(3*6)+(2*2)+(1*8)=95
95 % 10 = 5
So 956-28-5 is a valid CAS Registry Number.

The 2,1-Benzisothiazolo-2,1-benzisothiazole System, Synthesis and Properties

McKinnon, David M.,Duncan, K. Ann

, p. 1095 - 1098 (2007/10/02)

2,2'-Diaminodiphenylmethane and its 4,4'-dibromo-derivative both react with N-sulfinylmethanesulfonamide to form 2,1-benzisothiazole derivatives.Methylation or acetylation of these provides examples of the hypervalent sulfur 2,1-benzisothiazolo-2,1-benzisothiazole system.The nmr spectra of these compounds are discussed.
