Check Digit Verification of cas no
The CAS Registry Mumber 220407-34-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,4,0 and 7 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 220407-34:
(8*2)+(7*2)+(6*0)+(5*4)+(4*0)+(3*7)+(2*3)+(1*4)=81
81 % 10 = 1
So 220407-34-1 is a valid CAS Registry Number.
