Check Digit Verification of cas no

The CAS Registry Mumber 77721-99-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,7,2 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 77721-99:
(7*7)+(6*7)+(5*7)+(4*2)+(3*1)+(2*9)+(1*9)=164
164 % 10 = 4
So 77721-99-4 is a valid CAS Registry Number.

Direct Nitration of Aldehyde Arylhydrazones and the Use of the Products in the Synthesis of some Heterocyclic Compounds

Shawali, Ahmad S.,Hassaneen, Hamdi M.,Sherif, Sherif M.

, p. 1745 - 1749 (2007/10/02)

Direct nitration of substituted benzaldehyde p-nitrophenylhydrazones 1 gave α-nitroarylidene-p-nitrophenylhydrazines 2.Reactions of 2 with nucleophiles result in displacement of the nitrite.Treatment of 2 with potassium thiocyanate gave 5-imino-1,3,4-Δsu
