Check Digit Verification of cas no

The CAS Registry Mumber 1005339-34-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,5,3,3 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1005339-34:
(9*1)+(8*0)+(7*0)+(6*5)+(5*3)+(4*3)+(3*9)+(2*3)+(1*4)=103
103 % 10 = 3
So 1005339-34-3 is a valid CAS Registry Number.

Regulation of cyclization for the stereoselective synthesis of substituted tetrahydrofurans and tetrahydrooxepines

Kim, Sang-Hoon,Oh, Seung-Ju,Ho, Pil-Su,Kang, Sin-Cheol,O, Kyung-Jin,Yu, Chan-Mo

, p. 265 - 268 (2008)

(Chemical Equation Presented) Dramatic solvent effect is observed during the cyclization of 1. Synthesis of 2 is achieved from the reaction of 1 with a hexamethylditin-catalyzed palladium complex followed by aldehydes in the presence of TMSOTf in THF, whereas 3 is formed in CH2Cl2. The method described herein is successful with various substrates 1 in good yields and high levels of diastereoselectivity.
