18632-87-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 18632-87-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,6,3 and 2 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 18632-87:
(7*1)+(6*8)+(5*6)+(4*3)+(3*2)+(2*8)+(1*7)=126
126 % 10 = 6
So 18632-87-6 is a valid CAS Registry Number.
