1093240-29-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1093240-29-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,9,3,2,4 and 0 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1093240-29:
(9*1)+(8*0)+(7*9)+(6*3)+(5*2)+(4*4)+(3*0)+(2*2)+(1*9)=129
129 % 10 = 9
So 1093240-29-9 is a valid CAS Registry Number.
