18668-13-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 18668-13-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,6,6 and 8 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 18668-13:
(7*1)+(6*8)+(5*6)+(4*6)+(3*8)+(2*1)+(1*3)=138
138 % 10 = 8
So 18668-13-8 is a valid CAS Registry Number.
