Check Digit Verification of cas no

The CAS Registry Mumber 79164-20-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,1,6 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 79164-20:
(7*7)+(6*9)+(5*1)+(4*6)+(3*4)+(2*2)+(1*0)=148
148 % 10 = 8
So 79164-20-8 is a valid CAS Registry Number.

INTERCEPTION OF TETRAHEDRAL INTERMEDIATES IN Pd(II)-MEDIATED CYCLOALKENYLATIONS OF OLEFINIC ENOL ETHERS

Kende, Andrew S.,Wustrow, David J.

, p. 5411 - 5414 (2007/10/02)

The tetrahedral intermediate 3 has been intercepted during Pd(II)-cycloalkenylation of olefinic enolsilane 1 (R=SiMe2t-Bu).In a related manner, the allyl and crotyl enol ethers 5-8 give with Pd(OAc)2 acetoxy tetrahydrofurans (9, 12, 14, 16), convertible to butyrolactones or furans; competing Pd(II)-mediated Claisen rearrangement was not observed.The intramolecular Pd(II)-cycloalkenylation of the ketene acetal 17 leads to δ-lactones 18 and 19.
