94243-07-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 94243-07-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,2,4 and 3 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 94243-07:
(7*9)+(6*4)+(5*2)+(4*4)+(3*3)+(2*0)+(1*7)=129
129 % 10 = 9
So 94243-07-9 is a valid CAS Registry Number.
