77294-80-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77294-80-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,2,9 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 77294-80:
(7*7)+(6*7)+(5*2)+(4*9)+(3*4)+(2*8)+(1*0)=165
165 % 10 = 5
So 77294-80-5 is a valid CAS Registry Number.
