Check Digit Verification of cas no
The CAS Registry Mumber 742062-21-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,2,0,6 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 742062-21:
(8*7)+(7*4)+(6*2)+(5*0)+(4*6)+(3*2)+(2*2)+(1*1)=131
131 % 10 = 1
So 742062-21-1 is a valid CAS Registry Number.
