Check Digit Verification of cas no
The CAS Registry Mumber 136358-76-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,3,5 and 8 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 136358-76:
(8*1)+(7*3)+(6*6)+(5*3)+(4*5)+(3*8)+(2*7)+(1*6)=144
144 % 10 = 4
So 136358-76-4 is a valid CAS Registry Number.

A vicarious synthesis of unsymmetrical meta- and para- terphenyls from 2H-pyran-2-ones
Goel, Atul,Verma, Deepti,Singh, Fateh Veer
, p. 8487 - 8491 (2005)
An innovative synthesis of terphenyls functionalized with electron-withdrawing or -donating substituents is described and illustrated by carbanion-induced ring transformation of 2H-pyran-2-ones with 2-methoxyacetophenone in excellent yields. The existing
