109947-75-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109947-75-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,9,4 and 7 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 109947-75:
(8*1)+(7*0)+(6*9)+(5*9)+(4*4)+(3*7)+(2*7)+(1*5)=163
163 % 10 = 3
So 109947-75-3 is a valid CAS Registry Number.
