Check Digit Verification of cas no

The CAS Registry Mumber 78151-55-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,1,5 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 78151-55:
(7*7)+(6*8)+(5*1)+(4*5)+(3*1)+(2*5)+(1*5)=140
140 % 10 = 0
So 78151-55-0 is a valid CAS Registry Number.

Synthesis and Reactions of Perylenecarboxylic Acid Derivatives. VIII. Synthesis of N-Alkyl-3,4:9,10-Perylenetetracarboxylic Monoanhydride Monoimide

Nagao, Yukinori,Misono, Takahisa

, p. 1191 - 1194 (2007/10/02)

The condensations of 3,4:9,10-perylenetetracarboxylic dianhydride with alkylamines (isobutyl-, pentyl-, hexyl-, and octylamines) were spectroscopically determined.Under all of the reaction conditions employed, N-alkyl-3,4:9,10-perylenetetracarboxylic monoanhydride monoimide (2a-d) (alkyl=a; isobutyl, b; pentyl, c; hexyl, d; octyl) were obtained.As the reaction proceeded, the yield of 2a-d increased at an initial stage but decreased gradually after reaching a maximum.This maximum yield of 2a-d was: 2a; 85-88percent, 2b; 85-89percent, 2c; 78-84percent, 2d; 79-85percent.The kinetics of the reaction were also examined.
