Check Digit Verification of cas no
The CAS Registry Mumber 1011709-09-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,1,7,0 and 9 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1011709-09:
(9*1)+(8*0)+(7*1)+(6*1)+(5*7)+(4*0)+(3*9)+(2*0)+(1*9)=93
93 % 10 = 3
So 1011709-09-3 is a valid CAS Registry Number.
