Check Digit Verification of cas no
The CAS Registry Mumber 139932-01-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,9,3 and 2 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 139932-01:
(8*1)+(7*3)+(6*9)+(5*9)+(4*3)+(3*2)+(2*0)+(1*1)=147
147 % 10 = 7
So 139932-01-7 is a valid CAS Registry Number.
