The CAS Registry Mumber 2046-89-1 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 6 respectively; the second part has 2 digits, 8 and 9 respectively. Calculate Digit Verification of CAS Registry Number 2046-89: (6*2)+(5*0)+(4*4)+(3*6)+(2*8)+(1*9)=71 71 % 10 = 1 So 2046-89-1 is a valid CAS Registry Number.
