66549-82-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 66549-82-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,5,4 and 9 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 66549-82:
(7*6)+(6*6)+(5*5)+(4*4)+(3*9)+(2*8)+(1*2)=164
164 % 10 = 4
So 66549-82-4 is a valid CAS Registry Number.
