226070-80-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 226070-80-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,6,0,7 and 0 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 226070-80:
(8*2)+(7*2)+(6*6)+(5*0)+(4*7)+(3*0)+(2*8)+(1*0)=110
110 % 10 = 0
So 226070-80-0 is a valid CAS Registry Number.
