The CAS Registry Mumber 14957-78-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,9,5 and 7 respectively; the second part has 2 digits, 7 and 8 respectively. Calculate Digit Verification of CAS Registry Number 14957-78: (7*1)+(6*4)+(5*9)+(4*5)+(3*7)+(2*7)+(1*8)=139 139 % 10 = 9 So 14957-78-9 is a valid CAS Registry Number.
