82220-87-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 82220-87-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,2,2 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 82220-87:
(7*8)+(6*2)+(5*2)+(4*2)+(3*0)+(2*8)+(1*7)=109
109 % 10 = 9
So 82220-87-9 is a valid CAS Registry Number.
