49561-21-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 49561-21-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,5,6 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 49561-21:
(7*4)+(6*9)+(5*5)+(4*6)+(3*1)+(2*2)+(1*1)=139
139 % 10 = 9
So 49561-21-9 is a valid CAS Registry Number.
