Check Digit Verification of cas no

The CAS Registry Mumber 98004-04-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,0,0 and 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 98004-04:
(7*9)+(6*8)+(5*0)+(4*0)+(3*4)+(2*0)+(1*4)=127
127 % 10 = 7
So 98004-04-7 is a valid CAS Registry Number.

[3 + 2] annulation of allylic silanes in acyclic stereocontrol: Total synthesis of (9S)-dihydroerythronolide A

Peng, Zhi-Hui,Woerpel

, p. 6018 - 6019 (2007/10/03)

The [3 + 2] annulation reactions of allylic silanes can be utilized to achieve acyclic stereocontrol. This method was employed as a key step in an enantioselective total synthesis of (9S)-dihydroerythronolide A. The key annulation reaction served to estab
