The CAS Registry Mumber 2604-90-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,0 and 4 respectively; the second part has 2 digits, 9 and 0 respectively. Calculate Digit Verification of CAS Registry Number 2604-90: (6*2)+(5*6)+(4*0)+(3*4)+(2*9)+(1*0)=72 72 % 10 = 2 So 2604-90-2 is a valid CAS Registry Number.
