Check Digit Verification of cas no
The CAS Registry Mumber 312325-87-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,2,3,2 and 5 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 312325-87:
(8*3)+(7*1)+(6*2)+(5*3)+(4*2)+(3*5)+(2*8)+(1*7)=104
104 % 10 = 4
So 312325-87-4 is a valid CAS Registry Number.
