81879-31-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81879-31-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,8,7 and 9 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 81879-31:
(7*8)+(6*1)+(5*8)+(4*7)+(3*9)+(2*3)+(1*1)=164
164 % 10 = 4
So 81879-31-4 is a valid CAS Registry Number.
