77880-44-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77880-44-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,8,8 and 0 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 77880-44:
(7*7)+(6*7)+(5*8)+(4*8)+(3*0)+(2*4)+(1*4)=175
175 % 10 = 5
So 77880-44-5 is a valid CAS Registry Number.
