Check Digit Verification of cas no

The CAS Registry Mumber 162653-09-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,2,6,5 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 162653-09:
(8*1)+(7*6)+(6*2)+(5*6)+(4*5)+(3*3)+(2*0)+(1*9)=130
130 % 10 = 0
So 162653-09-0 is a valid CAS Registry Number.

Synthesis of a novel dual inhibitor of thromboxane A2 synthetase and 5- lipoxygenase (E3040) via the direct coupling reaction of hydroquinone with 3- pyridinecarboxaldehyde

Komatsu,Minami

, p. 1614 - 1616 (1995)

Synthesis of a novel dual inhibitor of thromboxane A2 synthetase and 5- lipoxygenase, 5,7-dimethyl-6-hydroxy-2-methylamino-4-(3- pyridylmethyl)benzothiazole (E3040), was accomplished via a new coupling reaction, in which a key intermediate, (3,6-dihydroxy-2,4-dimethylphenyl)- (3-pyridyl)methanol, was easily synthesized in a high yield from 2,6- dimethyl-1,4-benzohydroquinone and 3-pyridinecarboxaldehyde in 6 N hydrochloric acid. The regio isomers of 3-pyridinecarboxaldehyde also gave the corresponding coupling products in high yields.
