94142-71-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 94142-71-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,1,4 and 2 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 94142-71:
(7*9)+(6*4)+(5*1)+(4*4)+(3*2)+(2*7)+(1*1)=129
129 % 10 = 9
So 94142-71-9 is a valid CAS Registry Number.
