Check Digit Verification of cas no
The CAS Registry Mumber 108203-46-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,2,0 and 3 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 108203-46:
(8*1)+(7*0)+(6*8)+(5*2)+(4*0)+(3*3)+(2*4)+(1*6)=89
89 % 10 = 9
So 108203-46-9 is a valid CAS Registry Number.
