Check Digit Verification of cas no
The CAS Registry Mumber 164118-30-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,4,1,1 and 8 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 164118-30:
(8*1)+(7*6)+(6*4)+(5*1)+(4*1)+(3*8)+(2*3)+(1*0)=113
113 % 10 = 3
So 164118-30-3 is a valid CAS Registry Number.
