Check Digit Verification of cas no
The CAS Registry Mumber 122111-05-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,1,1 and 1 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 122111-05:
(8*1)+(7*2)+(6*2)+(5*1)+(4*1)+(3*1)+(2*0)+(1*5)=51
51 % 10 = 1
So 122111-05-1 is a valid CAS Registry Number.
