80056-47-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80056-47-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,0,5 and 6 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 80056-47:
(7*8)+(6*0)+(5*0)+(4*5)+(3*6)+(2*4)+(1*7)=109
109 % 10 = 9
So 80056-47-9 is a valid CAS Registry Number.
