90287-31-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90287-31-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,2,8 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 90287-31:
(7*9)+(6*0)+(5*2)+(4*8)+(3*7)+(2*3)+(1*1)=133
133 % 10 = 3
So 90287-31-3 is a valid CAS Registry Number.
