Check Digit Verification of cas no

The CAS Registry Mumber 1020107-05-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,0,1,0 and 7 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1020107-05:
(9*1)+(8*0)+(7*2)+(6*0)+(5*1)+(4*0)+(3*7)+(2*0)+(1*5)=54
54 % 10 = 4
So 1020107-05-4 is a valid CAS Registry Number.

Organocatalytic highly enantioselective tandem Michael-Knoevenagel reaction for the synthesis of substituted thiochromanes

Dodda, Rajasekhar,Mandal, Tanmay,Zhao, Cong-Gui

, p. 1899 - 1902 (2008/09/19)

Enantioenriched tetrasubstituted thiochromanes have been synthesized using a tandem Michael addition-Knoevenagel reaction between 2-mercaptobenzaldehydes and benzylidenemalonates with a 9-epi-aminoquinine thiourea derivative as the catalyst. Steric and electron effects were found to affect profoundly the enantioselectivity and diastereoselectivity of the reaction.
