71511-32-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 71511-32-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,5,1 and 1 respectively; the second part has 2 digits, 3 and 2 respectively.Calculate Digit Verification of CAS Registry Number 71511-32:
(7*7)+(6*1)+(5*5)+(4*1)+(3*1)+(2*3)+(1*2)=95
95 % 10 = 5
So 71511-32-5 is a valid CAS Registry Number.
