Check Digit Verification of cas no

The CAS Registry Mumber 57736-16-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,7,3 and 6 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 57736-16:
(7*5)+(6*7)+(5*7)+(4*3)+(3*6)+(2*1)+(1*6)=150
150 % 10 = 0
So 57736-16-0 is a valid CAS Registry Number.

Conjugated Schiff's Bases. 16-Substituent Effect on Electron Impact Fragmentation of Some 1-Oxa-4-azabutadienes

Moskal, Janusz,Moskal, Alexandra,Nagraba, Krzysztof

, p. 87 - 91 (2007/10/02)

The electron impact fragmentation patterns of some 1-oxa-4-azabutadienes have been determined and supported by the corresponding metastables.The effect of substituents on this fragmentation has been investigated.Satisfactory correlation of intensity ratios of the peaks characterizing the primary fragmentation versus the Brown and Okamoto ?+ substituent parameters has been found.The relationship between the substituent parameters and the dissociation energy ED,C(3)-C(5), estimated with the help of appearance energies has been considered.
