220041-95-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 220041-95-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,0,4 and 1 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 220041-95:
(8*2)+(7*2)+(6*0)+(5*0)+(4*4)+(3*1)+(2*9)+(1*5)=72
72 % 10 = 2
So 220041-95-2 is a valid CAS Registry Number.
