The CAS Registry Mumber 18476-31-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,4,7 and 6 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 18476-31:
(7*1)+(6*8)+(5*4)+(4*7)+(3*6)+(2*3)+(1*1)=128
128 % 10 = 8

Optimized procedures for one-pot conversion of alkyl bromides into amines via the Staudinger reaction

Koziara,Zwierzak

, p. 1063 - 1065 (2007/10/02)

New optimized procedures for transforming primary and secondary alkyl bromides into the corresponding primary amine salts have been elaborated. Essential modifications of azidation and deprotection of intermediate triethoxyphosphine alkylimides resulted in substantial improvement of the overall yields. Conversion of ammonium tosylates and hydrochlorides into free amines in a nonaqueous medium is described.
