Check Digit Verification of cas no

The CAS Registry Mumber 1257267-04-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,2,6 and 7 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1257267-04:
(9*1)+(8*2)+(7*5)+(6*7)+(5*2)+(4*6)+(3*7)+(2*0)+(1*4)=161
161 % 10 = 1
So 1257267-04-1 is a valid CAS Registry Number.

Base-Mediated Intramolecular Decarboxylative Synthesis of Alkylamines from Alkanoyloxycarbamates

Li, Peihe,Ma, Nuannuan,Wang, Zheng,Dai, Qipu,Hu, Changwen

, p. 8233 - 8240 (2018)

A general and effective method for the synthesis of alkylamine via intramolecular decarboxylation of alkanoyloxycarbamates is described. The alkanoyloxycarbamates are readily prepared with alkyl carboxylic acids and hydroxylamine. The reaction shows a broad range of substrates (primary and secondary alkyl) with functional tolerance, and the corresponding products were obtained in good yields under mild conditions.
