Check Digit Verification of cas no
The CAS Registry Mumber 139177-62-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,1,7 and 7 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 139177-62:
(8*1)+(7*3)+(6*9)+(5*1)+(4*7)+(3*7)+(2*6)+(1*2)=151
151 % 10 = 1
So 139177-62-1 is a valid CAS Registry Number.
