Check Digit Verification of cas no

The CAS Registry Mumber 1208117-61-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,8,1,1 and 7 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1208117-61:
(9*1)+(8*2)+(7*0)+(6*8)+(5*1)+(4*1)+(3*7)+(2*6)+(1*1)=116
116 % 10 = 6
So 1208117-61-6 is a valid CAS Registry Number.

Catalytic C-CN activation and asymmetric cyanoamidation of alkenes: Total syntheses of (+)-horsfiline, (-)-coerulescine, and (-)-esermethole

Reddy, Venkata Jaganmohan,Douglas, Christopher J.

experimental part, p. 4719 - 4729 (2010/08/06)

The detailed study of Pd-catalyzed asymmetric cyanoamidation is reported. Excellent enantioselectivities are attributed to a chiral phosphosphoramidite ligand synthesized in one step from the commercially available materials. Cyanoamidation substrates are easy to prepare from the corresponding anilines. The 3,3-disubstituted oxindole products bear all-carbon quaternary stereocenters and contain a nitrile and an amide, which are valuable functional handles for the synthesis of many indole-containing natural products. Cyanoamidation tolerates free N-H groups, as demonstrated by the successful use of cyanoamidation in the syntheses of (+)-horsfiline and (-)-coerulescine.
