Check Digit Verification of cas no
The CAS Registry Mumber 16203-25-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,2,0 and 3 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 16203-25:
(7*1)+(6*6)+(5*2)+(4*0)+(3*3)+(2*2)+(1*5)=71
71 % 10 = 1
So 16203-25-1 is a valid CAS Registry Number.
