Check Digit Verification of cas no

The CAS Registry Mumber 90923-07-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,9,2 and 3 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 90923-07:
(7*9)+(6*0)+(5*9)+(4*2)+(3*3)+(2*0)+(1*7)=132
132 % 10 = 2
So 90923-07-2 is a valid CAS Registry Number.

Synthesis of symmetric diester-functionalised Troeger's base analogues

Bhuiyan, M. Delower H.,Zhu, Kai-Xian,Jensen, Paul,Try, Andrew C.

supporting information; experimental part, p. 4662 - 4670 (2010/10/19)

The yields of ester-functionalised Troeger's base analogues are dramatically improved by incorporating an electron-donating group on the aromatic ring and/or enhancing solubil- ity of the aniline unit. In addition to 2,8-diester compounds, 1,7-, 3,9- and 4,10-diester-functionalised Troeger's base analogues have been prepared for the first time.
