109749-44-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109749-44-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,7,4 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 109749-44:
(8*1)+(7*0)+(6*9)+(5*7)+(4*4)+(3*9)+(2*4)+(1*4)=152
152 % 10 = 2
So 109749-44-2 is a valid CAS Registry Number.
