Check Digit Verification of cas no

The CAS Registry Mumber 5823-54-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,2 and 3 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 5823-54:
(6*5)+(5*8)+(4*2)+(3*3)+(2*5)+(1*4)=101
101 % 10 = 1
So 5823-54-1 is a valid CAS Registry Number.

Syntheses and transformations of substituted benzazolyl- and tetrazolyl(benzotriazol-1-yl)methanes

Katritzky, Alan R.,Aslan, Diana,Shcherbakova, Irina V.,Chen, Jie,Belyakov, Sergei A.

, p. 1107 - 1114 (2007/10/03)

Condensation reactions of o-hydroxy- and o-mercaptoanilines, and o-phenylenediamine with (benzotriazol-1-yl)acetic acid result in (1,3-benzazol-2-yl)(benzotriazol-1-yl)methanes. Cycloaddition of sodium azide to (benzotriazol-1-yl)acetonitrile leads to (1,2,3,4-tetrazol-5-yl)(benzotriazol-1-yl)methane. The diazolo-substituted benzotriazolylmethanes thus obtained were mono- and di-alkylated at the methylene group and the displacement of the benzotriazole group by nucleophiles was investigated.
