81399-95-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81399-95-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,3,9 and 9 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 81399-95:
(7*8)+(6*1)+(5*3)+(4*9)+(3*9)+(2*9)+(1*5)=163
163 % 10 = 3
So 81399-95-3 is a valid CAS Registry Number.
