71841-17-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 71841-17-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,8,4 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 71841-17:
(7*7)+(6*1)+(5*8)+(4*4)+(3*1)+(2*1)+(1*7)=123
123 % 10 = 3
So 71841-17-3 is a valid CAS Registry Number.
