1098-87-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1098-87-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,9 and 8 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1098-87:
(6*1)+(5*0)+(4*9)+(3*8)+(2*8)+(1*7)=89
89 % 10 = 9
So 1098-87-9 is a valid CAS Registry Number.
