Check Digit Verification of cas no
The CAS Registry Mumber 208345-25-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,8,3,4 and 5 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 208345-25:
(8*2)+(7*0)+(6*8)+(5*3)+(4*4)+(3*5)+(2*2)+(1*5)=119
119 % 10 = 9
So 208345-25-9 is a valid CAS Registry Number.
