Check Digit Verification of cas no
The CAS Registry Mumber 15139-76-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,1,3 and 9 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 15139-76:
(7*1)+(6*5)+(5*1)+(4*3)+(3*9)+(2*7)+(1*6)=101
101 % 10 = 1
So 15139-76-1 is a valid CAS Registry Number.
