Check Digit Verification of cas no

The CAS Registry Mumber 79899-58-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,8,9 and 9 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 79899-58:
(7*7)+(6*9)+(5*8)+(4*9)+(3*9)+(2*5)+(1*8)=224
224 % 10 = 4
So 79899-58-4 is a valid CAS Registry Number.

Synthesis of 4-tert-Butyl-1,1-dimethylindan and 7-tert-Butyl-3,3-dimethyl-1-indanone and a Comparison of Isomers

Eisenbraun, Edmund J.,Harms, Weldon M.,Palaniswamy, Venkatapuram A.,Chen, Hoffman H.,Porcaro, Peter J.,et al.

, p. 342 - 346 (1982)

4-tert-Butyl-1,1-dimethylindan was synthesized to help establish the identity of products (5- and 6-tert-butyl-1,1-dimethylindan as minor and major products, respectively) from the sulfuric acid catalyzed condensation of tert-butylbenzene and isoprene.NMR (1H and 13C) studies of these hydrocarbons and their corresponding indanones, obtained through chromic acid oxidation, provided structural proof.Gated decoupling experiments were crucial to complete assignment.
