66648-76-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 66648-76-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,6,4 and 8 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 66648-76:
(7*6)+(6*6)+(5*6)+(4*4)+(3*8)+(2*7)+(1*6)=168
168 % 10 = 8
So 66648-76-8 is a valid CAS Registry Number.
