33446-90-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 33446-90-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,4,4 and 6 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 33446-90:
(7*3)+(6*3)+(5*4)+(4*4)+(3*6)+(2*9)+(1*0)=111
111 % 10 = 1
So 33446-90-1 is a valid CAS Registry Number.
