Check Digit Verification of cas no

The CAS Registry Mumber 953822-10-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,3,8,2 and 2 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 953822-10:
(8*9)+(7*5)+(6*3)+(5*8)+(4*2)+(3*2)+(2*1)+(1*0)=181
181 % 10 = 1
So 953822-10-1 is a valid CAS Registry Number.

Catalytic asymmetric [4 + 2] cycloadditions of ketenes and N-thioacyl imines: Alternatives for direct Mannich reactions of enolizable imines

Xu, Xuan,Wang, Kan,Nelson, Scott G.

, p. 11690 - 11691 (2008/03/13)

Asymmetric cinchona alkaloid-catalyzed ketene-N-thioacyl imine cycloadditions afford enantioenriched cis-4,5-disubstituted 1,3-thiazin-6-one heterocycles with high absolute and relative stereocontrol. These cycloadditions enable a strategy for executing catalytic asymmetric direct Mannich additions to enolizable, unactivated imines. The ketene and imine reaction components are both generated in situ from readily available acid chlorides and α-amido sulfones, respectively. Copyright
