Check Digit Verification of cas no

The CAS Registry Mumber 7735-67-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,3 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 7735-67:
(6*7)+(5*7)+(4*3)+(3*5)+(2*6)+(1*7)=123
123 % 10 = 3
So 7735-67-3 is a valid CAS Registry Number.

Synthesis of heterocycles based on products of anion arylation of unsaturated compounds. 5. Reaction of 2-aryl-1,4-benzoquinones with thiourea

Obushak,Matiichuk,Martyak

, p. 909 - 915 (2001)

2-Aryl-1,4-benzoquinones, that can be obtained by arylation of quinone by arenediazonium salts, regioselectively react with thiourea in acid medium to form 7-aryl-5-hydroxy-1,3-benzoxathiol-2-ones. In the presence of excess arylquinones at room temperature, 2-amino-6-hydroxybenzothiazoles are formed in the same reaction.
