81968-19-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81968-19-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,9,6 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.Calculate Digit Verification of CAS Registry Number 81968-19:
(7*8)+(6*1)+(5*9)+(4*6)+(3*8)+(2*1)+(1*9)=166
166 % 10 = 6
So 81968-19-6 is a valid CAS Registry Number.
