90145-18-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90145-18-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,1,4 and 5 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 90145-18:
(7*9)+(6*0)+(5*1)+(4*4)+(3*5)+(2*1)+(1*8)=109
109 % 10 = 9
So 90145-18-9 is a valid CAS Registry Number.
