The CAS Registry Mumber 120942-91-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,9,4 and 2 respectively; the second part has 2 digits, 9 and 1 respectively. Calculate Digit Verification of CAS Registry Number 120942-91: (8*1)+(7*2)+(6*0)+(5*9)+(4*4)+(3*2)+(2*9)+(1*1)=108 108 % 10 = 8 So 120942-91-8 is a valid CAS Registry Number.
