Check Digit Verification of cas no
The CAS Registry Mumber 243984-87-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,3,9,8 and 4 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 243984-87:
(8*2)+(7*4)+(6*3)+(5*9)+(4*8)+(3*4)+(2*8)+(1*7)=174
174 % 10 = 4
So 243984-87-4 is a valid CAS Registry Number.
