221022-83-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 221022-83-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,0,2 and 2 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 221022-83:
(8*2)+(7*2)+(6*1)+(5*0)+(4*2)+(3*2)+(2*8)+(1*3)=69
69 % 10 = 9
So 221022-83-9 is a valid CAS Registry Number.
