94823-71-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 94823-71-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,8,2 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 94823-71:
(7*9)+(6*4)+(5*8)+(4*2)+(3*3)+(2*7)+(1*1)=159
159 % 10 = 9
So 94823-71-9 is a valid CAS Registry Number.
