Check Digit Verification of cas no

The CAS Registry Mumber 135984-48-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,9,8 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 135984-48:
(8*1)+(7*3)+(6*5)+(5*9)+(4*8)+(3*4)+(2*4)+(1*8)=164
164 % 10 = 4
So 135984-48-4 is a valid CAS Registry Number.

The Birch reduction - Dialkylation reaction of aromatic carboxylic acids. Identification of NaNH2 as the base responsible for the second alkylation

Guzman,Castanedo,Maldonado

, p. 1001 - 1012 (1991)

The Birch reduction-alkylation of 3,5-dimethoxybenzoic acid with excesses Na and EDtBr gives 1,4-diethyl-3,5-dimethoxy-2,5-cyclohexadiene carboxylic acid, 3. The base responsible for the alkylation at C-4 has been identified as NaNH2, generated
