909302-30-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 909302-30-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,9,3,0 and 2 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 909302-30:
(8*9)+(7*0)+(6*9)+(5*3)+(4*0)+(3*2)+(2*3)+(1*0)=153
153 % 10 = 3
So 909302-30-3 is a valid CAS Registry Number.
