77224-32-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77224-32-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,2,2 and 4 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 77224-32:
(7*7)+(6*7)+(5*2)+(4*2)+(3*4)+(2*3)+(1*2)=129
129 % 10 = 9
So 77224-32-9 is a valid CAS Registry Number.
