Check Digit Verification of cas no
The CAS Registry Mumber 90145-23-6 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, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 90145-23:
(7*9)+(6*0)+(5*1)+(4*4)+(3*5)+(2*2)+(1*3)=106
106 % 10 = 6
So 90145-23-6 is a valid CAS Registry Number.
