The CAS Registry Mumber 22134-20-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,1,3 and 4 respectively; the second part has 2 digits, 2 and 0 respectively. Calculate Digit Verification of CAS Registry Number 22134-20: (7*2)+(6*2)+(5*1)+(4*3)+(3*4)+(2*2)+(1*0)=59 59 % 10 = 9 So 22134-20-9 is a valid CAS Registry Number.
