Check Digit Verification of cas no
The CAS Registry Mumber 118745-63-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,7,4 and 5 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 118745-63:
(8*1)+(7*1)+(6*8)+(5*7)+(4*4)+(3*5)+(2*6)+(1*3)=144
144 % 10 = 4
So 118745-63-4 is a valid CAS Registry Number.
