666720-76-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 666720-76-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,6,7,2 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 666720-76:
(8*6)+(7*6)+(6*6)+(5*7)+(4*2)+(3*0)+(2*7)+(1*6)=189
189 % 10 = 9
So 666720-76-9 is a valid CAS Registry Number.
