Check Digit Verification of cas no
The CAS Registry Mumber 6632-77-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,3 and 2 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6632-77:
(6*6)+(5*6)+(4*3)+(3*2)+(2*7)+(1*7)=105
105 % 10 = 5
So 6632-77-5 is a valid CAS Registry Number.

DIPHENYLHYDROXYMETHYLATION OF 3-METHYLPYRIDINE N-OXIDE BY THE DIANIONS OF BENZHYDROL AND THE KETYLS OF BENZOPHENONE

The reaction of 3-methylpyridine N-oxide with with the disodium, dipotassium, and dilithium salts of benzhydrol, generated from benzophenone and two moles of the respective metal, and the analogous ketyls of benzophenone leads to the products from diphenylhydroxymethylation in the side chain and in the ring and also the product from deoxidation (3-methylpyridine)
