18671-57-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 18671-57-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,6,7 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 18671-57:
(7*1)+(6*8)+(5*6)+(4*7)+(3*1)+(2*5)+(1*7)=133
133 % 10 = 3
So 18671-57-3 is a valid CAS Registry Number.
