80077-69-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80077-69-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,0,7 and 7 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 80077-69:
(7*8)+(6*0)+(5*0)+(4*7)+(3*7)+(2*6)+(1*9)=126
126 % 10 = 6
So 80077-69-6 is a valid CAS Registry Number.
