77120-71-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77120-71-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,1,2 and 0 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 77120-71:
(7*7)+(6*7)+(5*1)+(4*2)+(3*0)+(2*7)+(1*1)=119
119 % 10 = 9
So 77120-71-9 is a valid CAS Registry Number.
