18782-45-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 18782-45-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,7,8 and 2 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 18782-45:
(7*1)+(6*8)+(5*7)+(4*8)+(3*2)+(2*4)+(1*5)=141
141 % 10 = 1
So 18782-45-1 is a valid CAS Registry Number.
