220567-39-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 220567-39-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,5,6 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 220567-39:
(8*2)+(7*2)+(6*0)+(5*5)+(4*6)+(3*7)+(2*3)+(1*9)=115
115 % 10 = 5
So 220567-39-5 is a valid CAS Registry Number.
