144464-90-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144464-90-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,4,6 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 144464-90:
(8*1)+(7*4)+(6*4)+(5*4)+(4*6)+(3*4)+(2*9)+(1*0)=134
134 % 10 = 4
So 144464-90-4 is a valid CAS Registry Number.
