124089-40-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 124089-40-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,0,8 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 124089-40:
(8*1)+(7*2)+(6*4)+(5*0)+(4*8)+(3*9)+(2*4)+(1*0)=113
113 % 10 = 3
So 124089-40-3 is a valid CAS Registry Number.
