The CAS Registry Mumber 134333-40-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,3,3 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 134333-40:
(8*1)+(7*3)+(6*4)+(5*3)+(4*3)+(3*3)+(2*4)+(1*0)=97
97 % 10 = 7
So 134333-40-7 is a valid CAS Registry Number.
