71728-47-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 71728-47-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,7,2 and 8 respectively; the second part has 2 digits, 4 and 7 respectively.Calculate Digit Verification of CAS Registry Number 71728-47:
(7*7)+(6*1)+(5*7)+(4*2)+(3*8)+(2*4)+(1*7)=137
137 % 10 = 7
So 71728-47-7 is a valid CAS Registry Number.
