324580-50-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 324580-50-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,4,5,8 and 0 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 324580-50:
(8*3)+(7*2)+(6*4)+(5*5)+(4*8)+(3*0)+(2*5)+(1*0)=129
129 % 10 = 9
So 324580-50-9 is a valid CAS Registry Number.
