Check Digit Verification of cas no

The CAS Registry Mumber 28322-52-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,3,2 and 2 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 28322-52:
(7*2)+(6*8)+(5*3)+(4*2)+(3*2)+(2*5)+(1*2)=103
103 % 10 = 3
So 28322-52-3 is a valid CAS Registry Number.

Synthesis of α-diazo-β-keto esters, phosphonates and sulfones via acylbenzotriazole-mediated acylation of a diazomethyl anion

Pramanik, Mukund M. D.,Rastogi, Namrata

supporting information, p. 11567 - 11571 (2015/12/04)

We report a method for the synthesis of α-diazo-β-keto esters, phosphonates and sulfones via acylation of corresponding diazomethyl anions with N-acylbenzotriazoles. The N-o-amino-acylbenzotriazoles exhibited an unprecedented transphosphorylation reaction
