Check Digit Verification of cas no

The CAS Registry Mumber 1643787-74-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,4,3,7,8 and 7 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1643787-74:
(9*1)+(8*6)+(7*4)+(6*3)+(5*7)+(4*8)+(3*7)+(2*7)+(1*4)=209
209 % 10 = 9
So 1643787-74-9 is a valid CAS Registry Number.

Rhodium-catalyzed carbonylative skeleton rearrangement of 1,4-enynes tethered by a cyclopropane group

Chen, Gen-Qiang,Tang, Xiang-Ying,Shi, Min

, p. 2311 - 2315 (2014)

The carbonylative skeleton rearrangement of 1,4 enynes tethered by a cyclopropane group proceeded smoothly in the presence of [Rh(CO)2Cl]2 under CO atmosphere to give the corresponding 1,2,4,5,6,7-hexahydrocyclopenta[a]inden-3(3bH)-o

Catalyst-dependent divergent synthesis of pyrroles from 3-alkynyl imine derivatives: A noncarbonylative and carbonylative approach

Chen, Gen-Qiang,Zhang, Xiao-Nan,Wei, Yin,Tang, Xiang-Ying,Shi, Min

, p. 8492 - 8497 (2014/08/18)

A novel Ru0- and RhI-catalyzed noncarbonylative and carbonylative cycloisomerization of readily available 3-alkynyl imine derivatives has been developed to provide 3,4-fused or nonfused pyrrole derivatives efficiently in moderate to
