49661-22-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 49661-22-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,6,6 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 49661-22:
(7*4)+(6*9)+(5*6)+(4*6)+(3*1)+(2*2)+(1*2)=145
145 % 10 = 5
So 49661-22-5 is a valid CAS Registry Number.
