66380-90-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 66380-90-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,3,8 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 66380-90:
(7*6)+(6*6)+(5*3)+(4*8)+(3*0)+(2*9)+(1*0)=143
143 % 10 = 3
So 66380-90-3 is a valid CAS Registry Number.
