81641-19-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81641-19-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,6,4 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 81641-19:
(7*8)+(6*1)+(5*6)+(4*4)+(3*1)+(2*1)+(1*9)=122
122 % 10 = 2
So 81641-19-2 is a valid CAS Registry Number.
