124209-84-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 124209-84-3 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 4 respectively.
Calculate Digit Verification of CAS Registry Number 124209-84:
(8*1)+(7*2)+(6*4)+(5*2)+(4*0)+(3*9)+(2*8)+(1*4)=103
103 % 10 = 3
So 124209-84-3 is a valid CAS Registry Number.
