220825-83-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 220825-83-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,8,2 and 5 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 220825-83:
(8*2)+(7*2)+(6*0)+(5*8)+(4*2)+(3*5)+(2*8)+(1*3)=112
112 % 10 = 2
So 220825-83-2 is a valid CAS Registry Number.
