Check Digit Verification of cas no

The CAS Registry Mumber 1221439-75-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,1,4,3 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1221439-75:
(9*1)+(8*2)+(7*2)+(6*1)+(5*4)+(4*3)+(3*9)+(2*7)+(1*5)=123
123 % 10 = 3
So 1221439-75-3 is a valid CAS Registry Number.

The tert-Butylsulfinamide lynchpin in transition-metal-mediated multiscaffold library synthesis

Bauer, Renato A.,Diblasi, Christine M.,Tan, Derek S.

, p. 2084 - 2087 (2010)

Figure presented A unified synthetic approach to diverse polycyclic scaffolds has been developed using transition-metal-mediated cycloaddition and cyclization reactions of enynes and diynes. The tert-butylsulfinamide group has been identified as a particularly versatile lynchpin in these reactions, with a reactivity profile uniquely suited for efficient, stereoselective substrate synthesis and downstream transformations. This approach provides 10 distinct, functionalized scaffold classes related to common core structures in alkaloid and terpenoid natural products.
