74163-10-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74163-10-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,1,6 and 3 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 74163-10:
(7*7)+(6*4)+(5*1)+(4*6)+(3*3)+(2*1)+(1*0)=113
113 % 10 = 3
So 74163-10-3 is a valid CAS Registry Number.
