Check Digit Verification of cas no

The CAS Registry Mumber 89521-22-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,5,2 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 89521-22:
(7*8)+(6*9)+(5*5)+(4*2)+(3*1)+(2*2)+(1*2)=152
152 % 10 = 2
So 89521-22-2 is a valid CAS Registry Number.

The Synthesis and hydrolysis of 6-exo-Substituted 2-Methyl-2-exo-norbornyl and 2-Methyl-2-endo-norbornyl 2,4-Dinitrophenyl Ethers

Grob, Cyril A.,Sprecher, Georg von,Waldner, Adrian

, p. 2656 - 2665 (1983)

The synthesis of the title compounds and their hydrolysis products in aqueous dioxane are described.Upon hydrolysis, the 2-exo-ethers 1 (X=N2phO) as well as the 2-endo-ethers 2 (X=N2phO) yield the corresponding 2-methyl-2-exo-norbornanols 3 only.Therefore
