Check Digit Verification of cas no
The CAS Registry Mumber 50662-99-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,6,6 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 50662-99:
(7*5)+(6*0)+(5*6)+(4*6)+(3*2)+(2*9)+(1*9)=122
122 % 10 = 2
So 50662-99-2 is a valid CAS Registry Number.
