Check Digit Verification of cas no

The CAS Registry Mumber 3684-39-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,8 and 4 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 3684-39:
(6*3)+(5*6)+(4*8)+(3*4)+(2*3)+(1*9)=107
107 % 10 = 7
So 3684-39-7 is a valid CAS Registry Number.

Carbon-13 NMR Study of Reaction of Aqueous Formaldehyde with Amine Salts: Evidences for Reductive Methylation by Intramolecular Hydride Transfer

Narasimhan, S.,Balakrishnan, M.,Kumar, A. S.,Venkatasubramanian, N.

, p. 568 - 570 (2007/10/02)

Reductive methylation of amine salts by aqueous formaldehyde under acidic conditions proceeds through the initial formation of hydroxymethylamine intermediates, followed by intramolecular hydride transfer. 13C NMR studies on this reaction and the mechanism are discussed.
