81307-81-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81307-81-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,3,0 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 81307-81:
(7*8)+(6*1)+(5*3)+(4*0)+(3*7)+(2*8)+(1*1)=115
115 % 10 = 5
So 81307-81-5 is a valid CAS Registry Number.
