Check Digit Verification of cas no
The CAS Registry Mumber 101973-14-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,1,9,7 and 3 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 101973-14:
(8*1)+(7*0)+(6*1)+(5*9)+(4*7)+(3*3)+(2*1)+(1*4)=102
102 % 10 = 2
So 101973-14-2 is a valid CAS Registry Number.

SYNTHESIS OF 7H-8,9-DIHYDRO-4,8-DIMETHYLPYRANOINDOL-2-ONES
Prasad, D. Vijaya,Darbarwar, Malleshwar
, p. 881 - 888 (2007/10/02)
The synthesis of pyrrolocoumarins viz., 7H-8,9-dihydro-4,8-dimethylpyranoindol-2-ones, a new tricyclic system (5), have been achieved from 7-amino-4-methylcoumarin (1) by tosylation, allylation and neat pyrolysis.A plausible mechanism involving ami
