Check Digit Verification of cas no

The CAS Registry Mumber 723252-00-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,3,2,5 and 2 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 723252-00:
(8*7)+(7*2)+(6*3)+(5*2)+(4*5)+(3*2)+(2*0)+(1*0)=124
124 % 10 = 4
So 723252-00-4 is a valid CAS Registry Number.

Synthesis of [1,2,4]triazolo[3,4-a]isoquinolines and pyrrolo[2,1-a]isoquinolines using α-keto hydrazonoyl halides

Elwan, Nehal M.,Abdelhadi, Hyam A.,Abdallah, Taysser A.,Hassaneen, Hamdi M.

, p. 3451 - 3456 (1996)

Treatment of α-keto hydrazonoyl halides 1 with 3,4-dihydro-6,7-dimethoxyisoquinoline 3 and its 1-methyl derivative 4 in the presence of triethylamine in tetrahydrofuran at reflux afforded the corresponding cycloadducts 6 and 9, respectively. The same halides 1 react with 1-cyanomethyl-3,4-dihydro-6,7-dimethoxyisoquinoline 5 and afforded pyrrolo[2,1-a]isoquinoline derivatives 12 in high yield.
