71838-49-8 Usage
Preparation
2-(4-Aminophenyl)-6-methylbenzo[d]thiazole-7-sulfonic acid diazo, and ?Barbituric acid?coupling.Check Digit Verification of cas no
The CAS Registry Mumber 71838-49-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,8,3 and 8 respectively; the second part has 2 digits, 4 and 9 respectively.Calculate Digit Verification of CAS Registry Number 71838-49:
(7*7)+(6*1)+(5*8)+(4*3)+(3*8)+(2*4)+(1*9)=148
148 % 10 = 8
So 71838-49-8 is a valid CAS Registry Number.
