90235-46-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90235-46-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,2,3 and 5 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 90235-46:
(7*9)+(6*0)+(5*2)+(4*3)+(3*5)+(2*4)+(1*6)=114
114 % 10 = 4
So 90235-46-4 is a valid CAS Registry Number.
