Check Digit Verification of cas no

The CAS Registry Mumber 191406-52-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,4,0 and 6 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 191406-52:
(8*1)+(7*9)+(6*1)+(5*4)+(4*0)+(3*6)+(2*5)+(1*2)=127
127 % 10 = 7
So 191406-52-7 is a valid CAS Registry Number.

Co(III)-salen catalyzed carbenoid reaction: Stereoselective [2,3]sigmatropic rearrangement of S-ylides derived from allyl aryl sulfides

Fukuda, Tsutomu,Katsuki, Tsutomu

, p. 3435 - 3438 (1997)

Allyl aryl sulfides and diazoacetic acid esters react in the presence of optically active Co(III)-salen complex (4) with good enantioselectivity, to give the [2,3]sigmatropic rearrangement products, 2-arylthio-3-aryl-4-pentenoic acid esters, via the corresponding S-ylides.
