90128-38-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90128-38-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,1,2 and 8 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 90128-38:
(7*9)+(6*0)+(5*1)+(4*2)+(3*8)+(2*3)+(1*8)=114
114 % 10 = 4
So 90128-38-4 is a valid CAS Registry Number.
