145664-99-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 145664-99-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,6,6 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 145664-99:
(8*1)+(7*4)+(6*5)+(5*6)+(4*6)+(3*4)+(2*9)+(1*9)=159
159 % 10 = 9
So 145664-99-9 is a valid CAS Registry Number.
