The CAS Registry Mumber 7727-44-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,2 and 7 respectively; the second part has 2 digits, 4 and 4 respectively. Calculate Digit Verification of CAS Registry Number 7727-44: (6*7)+(5*7)+(4*2)+(3*7)+(2*4)+(1*4)=118 118 % 10 = 8 So 7727-44-8 is a valid CAS Registry Number.
