Check Digit Verification of cas no

The CAS Registry Mumber 93593-09-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,5,9 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 93593-09:
(7*9)+(6*3)+(5*5)+(4*9)+(3*3)+(2*0)+(1*9)=160
160 % 10 = 0
So 93593-09-0 is a valid CAS Registry Number.

Aminohaloborane in Organic Synthesis. IX. Exclusive ortho Acylation Reaction of N-Monoaminoalkylanilines

Adachi, Makoto,Sasakura, Kazuyuki,Sugasawa, Tsutomu

, p. 1826 - 1835 (2007/10/02)

The exclusive ortho acylation reaction of aniline derivatives using boron trichloride made possible the one-step synthesis of 2-acyl-N-monoaminoalkylanilines (1) and the corresponding imines (2) from N-monoaminoalkylanilines, even in the case of compounds with a bulky substituent at the nitrogen atom.Conventional methods only give 1 via elaborate procedures.Keywords: regioselective reaction; 2-acylaniline derivative; 2-acylaniline-imine derivative; boron trichloride
