The CAS Registry Mumber 16784-55-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,7,8 and 4 respectively; the second part has 2 digits, 5 and 5 respectively. Calculate Digit Verification of CAS Registry Number 16784-55: (7*1)+(6*6)+(5*7)+(4*8)+(3*4)+(2*5)+(1*5)=137 137 % 10 = 7 So 16784-55-7 is a valid CAS Registry Number.
