87031-13-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87031-13-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,0,3 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 87031-13:
(7*8)+(6*7)+(5*0)+(4*3)+(3*1)+(2*1)+(1*3)=118
118 % 10 = 8
So 87031-13-8 is a valid CAS Registry Number.
