1989-31-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1989-31-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,8 and 9 respectively; the second part has 2 digits, 3 and 1 respectively.Calculate Digit Verification of CAS Registry Number 1989-31:
(6*1)+(5*9)+(4*8)+(3*9)+(2*3)+(1*1)=117
117 % 10 = 7
So 1989-31-7 is a valid CAS Registry Number.
