1093490-31-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1093490-31-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,9,3,4,9 and 0 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1093490-31:
(9*1)+(8*0)+(7*9)+(6*3)+(5*4)+(4*9)+(3*0)+(2*3)+(1*1)=153
153 % 10 = 3
So 1093490-31-3 is a valid CAS Registry Number.
