Check Digit Verification of cas no
The CAS Registry Mumber 1105709-22-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,0,5,7,0 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1105709-22:
(9*1)+(8*1)+(7*0)+(6*5)+(5*7)+(4*0)+(3*9)+(2*2)+(1*2)=115
115 % 10 = 5
So 1105709-22-5 is a valid CAS Registry Number.
