The CAS Registry Mumber 140926-92-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,9,2 and 6 respectively; the second part has 2 digits, 9 and 2 respectively. Calculate Digit Verification of CAS Registry Number 140926-92: (8*1)+(7*4)+(6*0)+(5*9)+(4*2)+(3*6)+(2*9)+(1*2)=127 127 % 10 = 7 So 140926-92-7 is a valid CAS Registry Number.
