1101720-99-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1101720-99-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,0,1,7,2 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1101720-99:
(9*1)+(8*1)+(7*0)+(6*1)+(5*7)+(4*2)+(3*0)+(2*9)+(1*9)=93
93 % 10 = 3
So 1101720-99-3 is a valid CAS Registry Number.
