Check Digit Verification of cas no

The CAS Registry Mumber 73177-40-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,1,7 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 73177-40:
(7*7)+(6*3)+(5*1)+(4*7)+(3*7)+(2*4)+(1*0)=129
129 % 10 = 9
So 73177-40-9 is a valid CAS Registry Number.

Reductive Alkylation of 2,5-Dimethoxybenzoic Acid: A Direct Synthesis of Dihydrofluoren-2-ones

Hook, James M.,Mander, Lewis N.

, p. 1722 - 1724 (2007/10/02)

A two-operation procedure is described for the synthesis of 3,4-dihydrofluoren-2(1H)-ones from "reductive alkylation" of 2,5-dimethoxybenzoic acid with benzyl halides, followed by cyclodehydration of the adducts, with concomitant decarboxylation.
