845531-18-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 845531-18-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,5,5,3 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 845531-18:
(8*8)+(7*4)+(6*5)+(5*5)+(4*3)+(3*1)+(2*1)+(1*8)=172
172 % 10 = 2
So 845531-18-2 is a valid CAS Registry Number.
