300382-89-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 300382-89-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,0,3,8 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 300382-89:
(8*3)+(7*0)+(6*0)+(5*3)+(4*8)+(3*2)+(2*8)+(1*9)=102
102 % 10 = 2
So 300382-89-2 is a valid CAS Registry Number.
