Check Digit Verification of cas no

The CAS Registry Mumber 70654-97-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,6,5 and 4 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 70654-97:
(7*7)+(6*0)+(5*6)+(4*5)+(3*4)+(2*9)+(1*7)=136
136 % 10 = 6
So 70654-97-6 is a valid CAS Registry Number.

Synthesis and Reactions of Perylenecarboxylic Acid Derivatives. VII. Hydrolysis of N,N'-Dialkyl-3,4:9,10-Perylenebis(dicarboximide) with Sulfuric Acid

Nagao, Yukinori,Misono, Takahisa

, p. 1269 - 1270 (2007/10/02)

The hydrolysis of N,N'-dialkyl-3,4:9,10-perylenebis(dicarboximide) (alkyl = CH3, CH2CH3, CH2CH2CH3, and CH2CH2CH2CH3) with sulfuric acid at 180 - 200 deg C gave N-alkyl-3,4:9,10-perylenetetracarboxylic monoanhydride monoimide (alkyl = CH3, CH2CH3, CH2CH2CH3, and CH2CH2CH2CH3).The kinetics of the reaction were determined spectroscopically.
