The CAS Registry Mumber 133740-20-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,7,4 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 133740-20:
(8*1)+(7*3)+(6*3)+(5*7)+(4*4)+(3*0)+(2*2)+(1*0)=102
102 % 10 = 2
So 133740-20-2 is a valid CAS Registry Number.
