The CAS Registry Mumber 2785-33-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,8 and 5 respectively; the second part has 2 digits, 3 and 3 respectively. Calculate Digit Verification of CAS Registry Number 2785-33: (6*2)+(5*7)+(4*8)+(3*5)+(2*3)+(1*3)=103 103 % 10 = 3 So 2785-33-3 is a valid CAS Registry Number.
