Check Digit Verification of cas no

The CAS Registry Mumber 124890-68-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,8,9 and 0 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 124890-68:
(8*1)+(7*2)+(6*4)+(5*8)+(4*9)+(3*0)+(2*6)+(1*8)=142
142 % 10 = 2
So 124890-68-2 is a valid CAS Registry Number.

Synthesis and 1,3-Dipolar Cycloaddition Reaction of Novel Heteropentalene Mesomeric Betaines, Pyrroloimidazole Mesomeric Betaines

Musicki, Branislav

, p. 910 - 918 (2007/10/02)

A series of novel heteropentalene mesomeric betaines, pyrroloimidazole mesomeric betaines (10a-i), were prepared by condensation of 2-formylpyrroles with aromatic imines.The mesomeric structures 10a-i are proposed on the basis of spectral and micro
