18481-95-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 18481-95-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,4,8 and 1 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 18481-95:
(7*1)+(6*8)+(5*4)+(4*8)+(3*1)+(2*9)+(1*5)=133
133 % 10 = 3
So 18481-95-3 is a valid CAS Registry Number.
