81816-68-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81816-68-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,8,1 and 6 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 81816-68:
(7*8)+(6*1)+(5*8)+(4*1)+(3*6)+(2*6)+(1*8)=144
144 % 10 = 4
So 81816-68-4 is a valid CAS Registry Number.
