666720-55-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 666720-55-4 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, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 666720-55:
(8*6)+(7*6)+(6*6)+(5*7)+(4*2)+(3*0)+(2*5)+(1*5)=184
184 % 10 = 4
So 666720-55-4 is a valid CAS Registry Number.
