80947-47-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80947-47-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,9,4 and 7 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 80947-47:
(7*8)+(6*0)+(5*9)+(4*4)+(3*7)+(2*4)+(1*7)=153
153 % 10 = 3
So 80947-47-3 is a valid CAS Registry Number.
