Check Digit Verification of cas no

The CAS Registry Mumber 1333237-99-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,3,2,3 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1333237-99:
(9*1)+(8*3)+(7*3)+(6*3)+(5*2)+(4*3)+(3*7)+(2*9)+(1*9)=142
142 % 10 = 2
So 1333237-99-2 is a valid CAS Registry Number.

L-Prolinol as a chiral auxiliary in the photochemical synthesis of a new aryltetraline lignan analogue

Krawczyk, Krzysztof K.,Madej, Daria,Maurin, Jan K.,Czarnocki, Zbigniew

, p. 1103 - 1107 (2011/10/04)

Prochiral (E,E)-fulgide 8 was reacted with l-prolinol to afford cyclic (M)-fulgamide 10 in a two step reaction sequence. The UV-light-driven photocyclization of 10 proceeded stereospecifically, giving lignan analogue 1 in 40% yield. The structure of 1 was
