220834-45-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 220834-45-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,8,3 and 4 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 220834-45:
(8*2)+(7*2)+(6*0)+(5*8)+(4*3)+(3*4)+(2*4)+(1*5)=107
107 % 10 = 7
So 220834-45-7 is a valid CAS Registry Number.
