1209003-49-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1209003-49-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,9,0,0 and 3 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1209003-49:
(9*1)+(8*2)+(7*0)+(6*9)+(5*0)+(4*0)+(3*3)+(2*4)+(1*9)=105
105 % 10 = 5
So 1209003-49-5 is a valid CAS Registry Number.
