Check Digit Verification of cas no

The CAS Registry Mumber 160661-43-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,0,6,6 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 160661-43:
(8*1)+(7*6)+(6*0)+(5*6)+(4*6)+(3*1)+(2*4)+(1*3)=118
118 % 10 = 8
So 160661-43-8 is a valid CAS Registry Number.

Stereoselective construction and synthetic applications of phenylthio substituted iodoolefins

Magriotis,Doyle,Kim

, p. 2541 - 2544 (1990)

(E)- and (Z)-Phenylthio substituted iodoolefins 1 and 2 have been synthesized stereoselectively via lower order stannylcuprate addition to and hydroalumination of appropriate alkyne precursors. Their utility in model studies on the synthesis of calichemic

NUCLEOPHILIC REACTION AT A VINYL CENTER. XXII. SYNTHESIS AND NUCLEOPHILIC VINYLIC SUBSTITUTION IN E-β-FLUOROVINYL ARYL SULFONES

Shainyan, B. A.,Mirskova, A. N.

, p. 61 - 66 (2007/10/02)

The reaction of potassium fluoride with E-β-bromovinyl aryl sulfones in the presence of 18-crown-6-ether leads to a mixture of the sulfones XC6H4SO2CH2CHF2 and E-XC6H4SO2CH=CHF, the ratio of which decreases in the order X=CH3, H, Cl, NO2.The kinetics of n
