71151-01-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 71151-01-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,1,5 and 1 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 71151-01:
(7*7)+(6*1)+(5*1)+(4*5)+(3*1)+(2*0)+(1*1)=84
84 % 10 = 4
So 71151-01-4 is a valid CAS Registry Number.
