Check Digit Verification of cas no

The CAS Registry Mumber 143169-65-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,1,6 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 143169-65:
(8*1)+(7*4)+(6*3)+(5*1)+(4*6)+(3*9)+(2*6)+(1*5)=127
127 % 10 = 7
So 143169-65-7 is a valid CAS Registry Number.

Intramolecular aldol condensation applied to D-glucose-derived δ-ketoaldehydes: Access to enantiomerically pure six-membered carbocycles

Tadano,Kanazawa,Takao,Ogawa

, p. 4283 - 4300 (2007/10/02)

An enantiomerically pure δ-ketoaldehyde 10, efficiently prepared from D-glucose, was subjected to an intramolecular aldol condensation. By using DBU as a base, the expecting aldol reaction took place smoothly giving the aldol 11 stereoselectively. Further
