1033717-22-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1033717-22-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,3,7,1 and 7 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1033717-22:
(9*1)+(8*0)+(7*3)+(6*3)+(5*7)+(4*1)+(3*7)+(2*2)+(1*2)=114
114 % 10 = 4
So 1033717-22-4 is a valid CAS Registry Number.
