Check Digit Verification of cas no

The CAS Registry Mumber 420810-54-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,0,8,1 and 0 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 420810-54:
(8*4)+(7*2)+(6*0)+(5*8)+(4*1)+(3*0)+(2*5)+(1*4)=104
104 % 10 = 4
So 420810-54-4 is a valid CAS Registry Number.

An efficient approach to α-aryl β-amino esters through 1,2-aryl migration of p-toluenesulfonic acid mediated diazo decomposition

Jiang,Wang

, p. 149 - 151 (2002)

A new method for the synthesis of α-aryl β-amino esters has been developed. The key step in this preparation is the chemoselective 1,2-aryl migration of diazo carbonyl compounds catalyzed by TsOH.
