71258-12-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 71258-12-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,2,5 and 8 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 71258-12:
(7*7)+(6*1)+(5*2)+(4*5)+(3*8)+(2*1)+(1*2)=113
113 % 10 = 3
So 71258-12-3 is a valid CAS Registry Number.
