124558-99-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 124558-99-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,5,5 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 124558-99:
(8*1)+(7*2)+(6*4)+(5*5)+(4*5)+(3*8)+(2*9)+(1*9)=142
142 % 10 = 2
So 124558-99-2 is a valid CAS Registry Number.
