81975-95-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81975-95-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,9,7 and 5 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 81975-95:
(7*8)+(6*1)+(5*9)+(4*7)+(3*5)+(2*9)+(1*5)=173
173 % 10 = 3
So 81975-95-3 is a valid CAS Registry Number.
