220032-91-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 220032-91-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,0,3 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 220032-91:
(8*2)+(7*2)+(6*0)+(5*0)+(4*3)+(3*2)+(2*9)+(1*1)=67
67 % 10 = 7
So 220032-91-7 is a valid CAS Registry Number.
