3989-60-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3989-60-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,8 and 9 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3989-60:
(6*3)+(5*9)+(4*8)+(3*9)+(2*6)+(1*0)=134
134 % 10 = 4
So 3989-60-4 is a valid CAS Registry Number.
