220657-11-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 220657-11-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,6,5 and 7 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 220657-11:
(8*2)+(7*2)+(6*0)+(5*6)+(4*5)+(3*7)+(2*1)+(1*1)=104
104 % 10 = 4
So 220657-11-4 is a valid CAS Registry Number.
