Check Digit Verification of cas no

The CAS Registry Mumber 1246451-95-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,6,4,5 and 1 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1246451-95:
(9*1)+(8*2)+(7*4)+(6*6)+(5*4)+(4*5)+(3*1)+(2*9)+(1*5)=155
155 % 10 = 5
So 1246451-95-5 is a valid CAS Registry Number.

Directions of reactions of 6-amino-, -acetylamino-, and- benzoylaminodeoxyvasicinones with aldehydes

Elmuradov,Abdurazakov,Shakhidoyatov

, p. 262 - 267 (2010)

6-Acetylamino- and -benzoylamino-9-arylidenedeoxyvasicinones were synthesized by reaction of 6-amino-(3), -acetylamino- (4), and -benzoylamino- (5) -deoxyvasicinones (DOV) with aromatic aldehydes and furfurol in glacial acetic acid. It was shown that the amino group of 6-aminodeoxyvasicinone underwent acylation upon reaction with aldehydes to form 6-acetylamino-DOV, which reacted with aldehydes to form 9-arylidene derivatives. Carrying out this condensation in toluene, o-xylene, and ethanol produced a mixture of condensation products at the 6-amino- and α-CH2-groups. It was found that condensati on of 3 with 4-nitrobenzaldehyde in pyridine formed exclusively the Schiff bases. Methods for preparing 6-nitrodeoxyvasicinone and for its reduction were improved.
