80442-77-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80442-77-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,4,4 and 2 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 80442-77:
(7*8)+(6*0)+(5*4)+(4*4)+(3*2)+(2*7)+(1*7)=119
119 % 10 = 9
So 80442-77-9 is a valid CAS Registry Number.
