Check Digit Verification of cas no

The CAS Registry Mumber 21132-29-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,1,3 and 2 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 21132-29:
(7*2)+(6*1)+(5*1)+(4*3)+(3*2)+(2*2)+(1*9)=56
56 % 10 = 6
So 21132-29-6 is a valid CAS Registry Number.

Electrochemical Hofmann rearrangement mediated by NaBr: Practical access to bioactive carbamates

Li, Lijun,Xue, Mengyu,Yan, Xin,Liu, Wenmin,Xu, Kun,Zhang, Sheng

, p. 4615 - 4618 (2018)

An electrochemical Hofmann rearrangement is reported. With the mediation of NaBr, highly corrosive and toxic halogens are avoided. Moreover, this efficient and green approach is well compatible with a broad range of amides, including several commercial medicine derivatives, and provides direct access to synthetically useful carbamates. The synthetic utility of this method is also demonstrated by the preparation of 15N labeling carbamate and gram-scale synthesis of Amantadine.
