Check Digit Verification of cas no

The CAS Registry Mumber 1229403-09-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,9,4,0 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1229403-09:
(9*1)+(8*2)+(7*2)+(6*9)+(5*4)+(4*0)+(3*3)+(2*0)+(1*9)=131
131 % 10 = 1
So 1229403-09-1 is a valid CAS Registry Number.

Amphipathic α-helix mimetics based on a 1,2-diphenylacetylene scaffold

Jung, Kwan-Young,Vanommeslaeghe, Kenno,Lanning, Maryanna E.,Yap, Jeremy L.,Gordon, Caryn,Wilder, Paul T.,Mackerell, Alexander D.,Fletcher, Steven

, p. 3234 - 3237 (2013)

In order to mimic amphipathic α-helices, a novel scaffold based on a 1,2-diphenylacetylene was designed. NMR and computational modeling confirmed that an intramolecular hydrogen bond favors conformations of the 1,2-diphenylacetylene that allow for accurat

Cyclopropylmethyl Protection of Phenols: Total Synthesis of the Resveratrol Dimers Anigopreissin A and Resveratrol–Piceatannol Hybrid

Kumar, Arvind,Saleeb, Michael,Werz, Dominik,Elofsson, Mikael

, p. 953 - 956 (2018/11/23)

We demonstrate the versatile use of the cyclopropylmethyl group to protect phenols through the total synthesis of two benzofuran-based natural products, that is, anigopreissin A and the resveratrol–piceatannol hybrid. This protecting group is a good alter
