Check Digit Verification of cas no
The CAS Registry Mumber 220951-81-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,9,5 and 1 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 220951-81:
(8*2)+(7*2)+(6*0)+(5*9)+(4*5)+(3*1)+(2*8)+(1*1)=115
115 % 10 = 5
So 220951-81-5 is a valid CAS Registry Number.
