109491-14-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 109491-14-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,4,9 and 1 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 109491-14:
(8*1)+(7*0)+(6*9)+(5*4)+(4*9)+(3*1)+(2*1)+(1*4)=127
127 % 10 = 7
So 109491-14-7 is a valid CAS Registry Number.
