107642-77-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 107642-77-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,6,4 and 2 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 107642-77:
(8*1)+(7*0)+(6*7)+(5*6)+(4*4)+(3*2)+(2*7)+(1*7)=123
123 % 10 = 3
So 107642-77-3 is a valid CAS Registry Number.

SIGMATROPIC REARRANGEMENT OF ARYLHYDRAZONES FOLLOWED BY 1,2-SHIFT OF AN ARYL GROUP. VII
Sannicolo, Franco
, p. 91 - 96 (2007/10/02)
Arylhydrazones of ethyl 4-methoxy-3,5-dimethylphenylglyoxylate and 4-methoxy-3,5-dimethylacetophenone rearrange in hot polyphosphoric acid to give biphenyl derivatives arising from a sigmatropic rearrangement followed by an aryl group 1,2-shift.Stru
