90302-21-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90302-21-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,3,0 and 2 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 90302-21:
(7*9)+(6*0)+(5*3)+(4*0)+(3*2)+(2*2)+(1*1)=89
89 % 10 = 9
So 90302-21-9 is a valid CAS Registry Number.
