1220020-65-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1220020-65-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,0,0,2 and 0 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1220020-65:
(9*1)+(8*2)+(7*2)+(6*0)+(5*0)+(4*2)+(3*0)+(2*6)+(1*5)=64
64 % 10 = 4
So 1220020-65-4 is a valid CAS Registry Number.
