Check Digit Verification of cas no
The CAS Registry Mumber 203580-20-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,5,8 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 203580-20:
(8*2)+(7*0)+(6*3)+(5*5)+(4*8)+(3*0)+(2*2)+(1*0)=95
95 % 10 = 5
So 203580-20-5 is a valid CAS Registry Number.
