Check Digit Verification of cas no

The CAS Registry Mumber 116139-10-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,1,3 and 9 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 116139-10:
(8*1)+(7*1)+(6*6)+(5*1)+(4*3)+(3*9)+(2*1)+(1*0)=97
97 % 10 = 7
So 116139-10-7 is a valid CAS Registry Number.

THE STEREOCHEMISTRY OF DIELS-ALDER REACTIONS OF CYCLOPROPENES

Apeloig, Yitzhak,Arad, Dorit,Kapon, Moshe,Wallerstein, Mercedes

, p. 5917 - 5920 (1987)

The stereochemistry of the Diels-Alder reactions of 3 cyclopropenes was determined unequivocally by X-ray and NOE studies.Tetrachlorocyclopropene yields exo-adducts with (E)-1-R-1,3-butadiene (R=OCH3, OCOCH3, OSiMe3), with 1,4-diphenylbutadiene and with furan. 1,2-bromochlorocyclopropene yields with (E)-1-R-butadienes (R=OCH3, OSiMe3) endo:exo-adducts in a ratio of 9:1.Cyclopropene + 1-methoxybutadiene yield only the endo-adduct.
