Check Digit Verification of cas no

The CAS Registry Mumber 273933-21-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,3,9,3 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 273933-21:
(8*2)+(7*7)+(6*3)+(5*9)+(4*3)+(3*3)+(2*2)+(1*1)=154
154 % 10 = 4
So 273933-21-4 is a valid CAS Registry Number.

Rapid synthesis of N-acyl ureas from their thio analogues using wet silica-supported permanganate under solvent-free conditions

Li, Zheng,Yu, Jin-Lan,Shi, Sheng-Yi,Zhu, Wei

, p. 1031 - 1037 (2006)

A rapid method to N-acyl ureas from corresponding N-acyl thioureas is described. N-coumaroyl-N′-arylthioureas, which are easily prepared by the reaction of coumarin-3-carboxylic acid chloride with potassium thiocyanate and arylamines, can be expeditiously
