872874-37-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 872874-37-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,2,8,7 and 4 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 872874-37:
(8*8)+(7*7)+(6*2)+(5*8)+(4*7)+(3*4)+(2*3)+(1*7)=218
218 % 10 = 8
So 872874-37-8 is a valid CAS Registry Number.

Enantioselective C-C bond formation to sulfonylimines through use of the 2-pyridinesulfonyl group as a novel stereocontroller

scheme or table, p. 2145 - 2152 (2009/04/08)

Enantioselective C-C bond formation to 2-pyridinesulfonylimines afforded products with good enantioselectivity. Dynamic induction of chirality on the sulfur by coordination of a chiral Lewis acid to the pyridine nitrogen and one of the prochiral sulfonyl oxygens induces enantioselectivity. Since the 2-pyridine-sulfonyl group can easily be removed after the reaction, it acts not only as an activating group but also as an efficient Stereocontroller.
