Check Digit Verification of cas no

The CAS Registry Mumber 1378878-13-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,8,8,7 and 8 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1378878-13:
(9*1)+(8*3)+(7*7)+(6*8)+(5*8)+(4*7)+(3*8)+(2*1)+(1*3)=227
227 % 10 = 7
So 1378878-13-7 is a valid CAS Registry Number.

A direct catalytic asymmetric aldol reaction of α-sulfanyl lactones: Efficient synthesis of SPT inhibitors

Takechi, Sho,Yasuda, Shigeo,Kumagai, Naoya,Shibasaki, Masakatsu

, p. 4218 - 4222 (2012/06/01)

Softly does it: The title reaction, catalyzed by a AgPF6/(R)- biphep-type ligand/DBU complex, is described (see scheme). This protocol gives efficient access to syn-configured α-sulfanyl-β-hydroxy lactones in a highly enantioselective manner. In one particular case, the sulfide group was stereospecifically replaced with a hydroxy group to afford an enantioenriched tertiary alcohol, which upon further manipulation led to a class of densely functionalized SPT inhibitors.
