The CAS Registry Mumber 2992-34-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,9 and 2 respectively; the second part has 2 digits, 3 and 4 respectively. Calculate Digit Verification of CAS Registry Number 2992-34: (6*2)+(5*9)+(4*9)+(3*2)+(2*3)+(1*4)=109 109 % 10 = 9 So 2992-34-9 is a valid CAS Registry Number.
