Check Digit Verification of cas no
The CAS Registry Mumber 123488-87-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,4,8 and 8 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 123488-87:
(8*1)+(7*2)+(6*3)+(5*4)+(4*8)+(3*8)+(2*8)+(1*7)=139
139 % 10 = 9
So 123488-87-9 is a valid CAS Registry Number.
