66489-90-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 66489-90-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,4,8 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 66489-90:
(7*6)+(6*6)+(5*4)+(4*8)+(3*9)+(2*9)+(1*0)=175
175 % 10 = 5
So 66489-90-5 is a valid CAS Registry Number.
