124209-89-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 124209-89-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,2,0 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 124209-89:
(8*1)+(7*2)+(6*4)+(5*2)+(4*0)+(3*9)+(2*8)+(1*9)=108
108 % 10 = 8
So 124209-89-8 is a valid CAS Registry Number.
