Check Digit Verification of cas no

The CAS Registry Mumber 149979-20-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,9,7 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 149979-20:
(8*1)+(7*4)+(6*9)+(5*9)+(4*7)+(3*9)+(2*2)+(1*0)=194
194 % 10 = 4
So 149979-20-4 is a valid CAS Registry Number.

PHOTOCHEMICAL TRANSFORMATIONS OF 2,4,4,6-TETRAPHENYL-4H-THIOPYRAN-1,1-DIOXIDE AND SOME ITS para-SUBSTITUTED DERIVATIVES

Sebek, Pavel,Sedmera, Petr,Kuthan, Josef

, p. 869 - 881 (2007/10/02)

1,2,4,5-Tetrasubstituted cyclopentadienes VIa - VIf or phenanthrene derivative VIII, respectively, were obtained as the main photoproducts upon irradiation of sulfones Ia - If and II in acetonitrile, methanol or benzene.Bridged isomers Va - Vd were isolated from the reaction of Ia - Id carried out in acetonitrile.Probable course of the investigated photochemical transformations of 4H-thiopyran-1,1-dioxides is discussed.
