1040140-56-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1040140-56-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,0,1,4 and 0 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1040140-56:
(9*1)+(8*0)+(7*4)+(6*0)+(5*1)+(4*4)+(3*0)+(2*5)+(1*6)=74
74 % 10 = 4
So 1040140-56-4 is a valid CAS Registry Number.

De novo asymmetric synthesis of anthrax tetrasaccharide and related tetrasaccharide
Guo, Haibing,O'Doherty, George A.
, p. 5211 - 5220 (2008/12/21)
(Chemical Equation Presented) A de novo asymmetric approach to the natural product anthrax tetrasaccharide 1 and an analogue 2 with an anomeric hexyl azide group has been developed from acetylfuran. The construction of the tetrasaccharide was achieved by
