Check Digit Verification of cas no
The CAS Registry Mumber 145057-71-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,0,5 and 7 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 145057-71:
(8*1)+(7*4)+(6*5)+(5*0)+(4*5)+(3*7)+(2*7)+(1*1)=122
122 % 10 = 2
So 145057-71-2 is a valid CAS Registry Number.
