305801-89-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 305801-89-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,5,8,0 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 305801-89:
(8*3)+(7*0)+(6*5)+(5*8)+(4*0)+(3*1)+(2*8)+(1*9)=122
122 % 10 = 2
So 305801-89-2 is a valid CAS Registry Number.
