1146-87-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1146-87-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,4 and 6 respectively; the second part has 2 digits, 8 and 7 respectively.Calculate Digit Verification of CAS Registry Number 1146-87:
(6*1)+(5*1)+(4*4)+(3*6)+(2*8)+(1*7)=68
68 % 10 = 8
So 1146-87-8 is a valid CAS Registry Number.
