874198-18-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 874198-18-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,4,1,9 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 874198-18:
(8*8)+(7*7)+(6*4)+(5*1)+(4*9)+(3*8)+(2*1)+(1*8)=212
212 % 10 = 2
So 874198-18-2 is a valid CAS Registry Number.
