Check Digit Verification of cas no
The CAS Registry Mumber 432020-60-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,2,0,2 and 0 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 432020-60:
(8*4)+(7*3)+(6*2)+(5*0)+(4*2)+(3*0)+(2*6)+(1*0)=85
85 % 10 = 5
So 432020-60-5 is a valid CAS Registry Number.
