The CAS Registry Mumber 7040-27-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,0,4 and 0 respectively; the second part has 2 digits, 2 and 7 respectively. Calculate Digit Verification of CAS Registry Number 7040-27: (6*7)+(5*0)+(4*4)+(3*0)+(2*2)+(1*7)=69 69 % 10 = 9 So 7040-27-9 is a valid CAS Registry Number.
