Check Digit Verification of cas no

The CAS Registry Mumber 129352-78-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,3,5 and 2 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 129352-78:
(8*1)+(7*2)+(6*9)+(5*3)+(4*5)+(3*2)+(2*7)+(1*8)=139
139 % 10 = 9
So 129352-78-9 is a valid CAS Registry Number.

SYNTHESIS OF 4,5,6,7-TETRAPHENYL-8(SUBSTITUTED-3(2H)-PHTHALAZINONE DERIVATIVES WITH POTENTIAL ANTIHYPERTENSIVE ACTIVITY

Yassin, F. A.,El-Safty, M. A.,Bayoumy, B. E.,Farargy, A. F. El

, p. 201 - 208 (2007/10/03)

The interaction of tetraphenylphthalic anhydride with o-chlorotoluene under Friedel-Crafts conditions gives 2-(4-chloro-3-methyl)benzoyl-3,4,5,6-tetraphenyl benzoic acid (1) which on reaction with hydrazine derivatives gave phthalazinones 2a-d. The behaviour of 2a towards carbon electrophiles and carbon nucleophiles has been investigated. The chlorophthalazinone 3s has been also synthesised through the action of PCl5/POCl3 on 2a. The behaviour of 3s towards nitrogen, and oxygen nucleophiles also has been described.
