Check Digit Verification of cas no
The CAS Registry Mumber 245759-71-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,5,7,5 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 245759-71:
(8*2)+(7*4)+(6*5)+(5*7)+(4*5)+(3*9)+(2*7)+(1*1)=171
171 % 10 = 1
So 245759-71-1 is a valid CAS Registry Number.
