139988-41-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 139988-41-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,9,8 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 139988-41:
(8*1)+(7*3)+(6*9)+(5*9)+(4*8)+(3*8)+(2*4)+(1*1)=193
193 % 10 = 3
So 139988-41-3 is a valid CAS Registry Number.
