Check Digit Verification of cas no

The CAS Registry Mumber 97195-28-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,1,9 and 5 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 97195-28:
(7*9)+(6*7)+(5*1)+(4*9)+(3*5)+(2*2)+(1*8)=173
173 % 10 = 3
So 97195-28-3 is a valid CAS Registry Number.

Self-Catalyzed Rapid Synthesis of N-Acylated/ N-Formylated α-Aminoketones and N-Hydroxymethylated Formamides from 3-Aryl-2 H-Azirines and 2-Me/Ph-3-Aryl-2 H-Azirines

A rapid and effective method has been established for the synthesis of N-acylated α-aminoketone derivatives by the reaction of 3-aryl-2H-azirines and highly substituted 2-Me/Ph-3-aryl-2H-azirines with various carboxylic acids under ambient air within 10 min at room temperature. N-Trifluoroacetylated α-aminoketones with different substituents have been reported in the presence of trifluoroacetic acid. This protocol is equally effective to synthesize N-formylated α-aminoketone and N-hydroxymethylated formamide derivatives.
