Check Digit Verification of cas no

The CAS Registry Mumber 136744-06-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,7,4 and 4 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 136744-06:
(8*1)+(7*3)+(6*6)+(5*7)+(4*4)+(3*4)+(2*0)+(1*6)=134
134 % 10 = 4
So 136744-06-4 is a valid CAS Registry Number.

Studies on hypotensive agents. Synthesis of 1-substituted 3-(2-chlorophenyl)-6-ethoxycarbonyl-5,7-dimethyl-2,4(1H,3H)- quinazolinediones

Eguchi,Sasaki,Sugimoto,Ebisawa,Ishikawa

, p. 1753 - 1759 (2007/10/02)

3-(2-Chlorophenyl)-6-ethoxycarbonyl-5,7-dimethyl-2,4(1H,3H)- quinazolinedione was newly prepared. 1-Hydrogen atoms of the compound were variously substituted in order to test for their hypotensive activities on relaxing effects of the blood vessels. The compounds with 2-(1-pyrrolidinyl ethyl, 2-(1-piperidinyl)ethyl, 3-(dimethylamino)propyl, and 3-(N-benzyl-N-methylamino)propyl moieties showed significant activity. The 2-(1-piperidinyl)ethyl compound possessed activity approximately 23 times more potent than papaverine, however, it was less potent than cinnarizine.
