809-01-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 809-01-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,0 and 9 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 809-01:
(5*8)+(4*0)+(3*9)+(2*0)+(1*1)=68
68 % 10 = 8
So 809-01-8 is a valid CAS Registry Number.
