2049-22-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2049-22-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,4 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2049-22:
(6*2)+(5*0)+(4*4)+(3*9)+(2*2)+(1*2)=61
61 % 10 = 1
So 2049-22-1 is a valid CAS Registry Number.
