Check Digit Verification of cas no
The CAS Registry Mumber 3989-75-1 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, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 3989-75:
(6*3)+(5*9)+(4*8)+(3*9)+(2*7)+(1*5)=141
141 % 10 = 1
So 3989-75-1 is a valid CAS Registry Number.
