94243-10-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 94243-10-4 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, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 94243-10:
(7*9)+(6*4)+(5*2)+(4*4)+(3*3)+(2*1)+(1*0)=124
124 % 10 = 4
So 94243-10-4 is a valid CAS Registry Number.
