Check Digit Verification of cas no
The CAS Registry Mumber 303183-89-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,3,1,8 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 303183-89:
(8*3)+(7*0)+(6*3)+(5*1)+(4*8)+(3*3)+(2*8)+(1*9)=113
113 % 10 = 3
So 303183-89-3 is a valid CAS Registry Number.
