1312573-20-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1312573-20-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,2,5,7 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1312573-20:
(9*1)+(8*3)+(7*1)+(6*2)+(5*5)+(4*7)+(3*3)+(2*2)+(1*0)=118
118 % 10 = 8
So 1312573-20-8 is a valid CAS Registry Number.

Triflic acid-mediated phenylation of N-acylaminoalkyl diethylacetals and N-acyl-2-phenyl cyclic amides
King, Frank D.,Caddick, Stephen
, p. 4361 - 4366 (2011/07/29)
The reaction of N-acylaminoalkyl diethylacetals with triflic acid in benzene gave N-acylamino-diphenylalkyls. The proposed intermediates are the N-acyl-2-phenyl cyclic amides, which themselves are similarly converted to N-acylamino-diphenylalkyls.
