18855-55-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 18855-55-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,8,5 and 5 respectively; the second part has 2 digits, 5 and 5 respectively.Calculate Digit Verification of CAS Registry Number 18855-55:
(7*1)+(6*8)+(5*8)+(4*5)+(3*5)+(2*5)+(1*5)=145
145 % 10 = 5
So 18855-55-5 is a valid CAS Registry Number.
