22222-81-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 22222-81-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,2,2 and 2 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 22222-81:
(7*2)+(6*2)+(5*2)+(4*2)+(3*2)+(2*8)+(1*1)=67
67 % 10 = 7
So 22222-81-7 is a valid CAS Registry Number.
