380431-21-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 380431-21-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,8,0,4,3 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 380431-21:
(8*3)+(7*8)+(6*0)+(5*4)+(4*3)+(3*1)+(2*2)+(1*1)=120
120 % 10 = 0
So 380431-21-0 is a valid CAS Registry Number.

Synthesis and some transformations of 2-(2′-thienyl)benzothiazole
Aleksandrov,El'Chaninov
, p. 1602 - 1606 (2011/02/16)
Condensation of ortho-aminothiophenol with 2-thenoyl chloride in 1-methyl-2-pyrrolidone was used to synthesize 2-(2′-thienyl)benzothiazole. Its reactions of electrophilic (nitration, bromination, oxymethylation, formylation, acylation) and radical (nitration, arylation) substitution were studied.
