Check Digit Verification of cas no
The CAS Registry Mumber 220430-09-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,4,3 and 0 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 220430-09:
(8*2)+(7*2)+(6*0)+(5*4)+(4*3)+(3*0)+(2*0)+(1*9)=71
71 % 10 = 1
So 220430-09-1 is a valid CAS Registry Number.
