Check Digit Verification of cas no
The CAS Registry Mumber 18472-87-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,4,7 and 2 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 18472-87:
(7*1)+(6*8)+(5*4)+(4*7)+(3*2)+(2*8)+(1*7)=132
132 % 10 = 2
So 18472-87-2 is a valid CAS Registry Number.
