Check Digit Verification of cas no
The CAS Registry Mumber 107711-03-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,7,1 and 1 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 107711-03:
(8*1)+(7*0)+(6*7)+(5*7)+(4*1)+(3*1)+(2*0)+(1*3)=95
95 % 10 = 5
So 107711-03-5 is a valid CAS Registry Number.
