105949-45-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 105949-45-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,9,4 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 105949-45:
(8*1)+(7*0)+(6*5)+(5*9)+(4*4)+(3*9)+(2*4)+(1*5)=139
139 % 10 = 9
So 105949-45-9 is a valid CAS Registry Number.
