Check Digit Verification of cas no

The CAS Registry Mumber 134723-99-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,7,2 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 134723-99:
(8*1)+(7*3)+(6*4)+(5*7)+(4*2)+(3*3)+(2*9)+(1*9)=132
132 % 10 = 2
So 134723-99-2 is a valid CAS Registry Number.

Heterocyclic Betaines. 13. Synthesis and Electronic and Molecular Structures of Methylenepyridinium and Methyleneimidazolium Azolate Inner Salts

Alcalde, Ermitas,Perez-Garcia, Lluisa,Miravitlles, Carlos,Rius, Jordi,Valenti, Eduard

, p. 4829 - 4834 (2007/10/02)

A convenient synthesis of several examples of betaines 3 and 4 is reported.The electronic and molecular structure of the title betaines 3 and 4 is investigated in terms of a single-crystal diffraction X-ray analysis of compound 7, spectroscopic methods, and experimental dipole moment values (12.34-15.34 D).Semiempirical molecular orbital calculations (MNDO and AM1 methods) provide a useful complementary information to the experimental results.
