109049-38-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109049-38-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,0,4 and 9 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 109049-38:
(8*1)+(7*0)+(6*9)+(5*0)+(4*4)+(3*9)+(2*3)+(1*8)=119
119 % 10 = 9
So 109049-38-9 is a valid CAS Registry Number.
