Check Digit Verification of cas no

The CAS Registry Mumber 1260158-09-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,0,1,5 and 8 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1260158-09:
(9*1)+(8*2)+(7*6)+(6*0)+(5*1)+(4*5)+(3*8)+(2*0)+(1*9)=125
125 % 10 = 5
So 1260158-09-5 is a valid CAS Registry Number.

Total synthesis of (±)-armepavines and (±)-nuciferines from (2-nitroethenyl)benzene derivatives

Chang, Chia-Fu,Huang, Chu-Yun,Huang, Yu-Chao,Lin, Kuan-Yu,Lee, Yean-Jang,Wang, Chau-Jong

experimental part, p. 3452 - 3466 (2011/02/22)

A concise route to armepavine 1 and nuciferine 2 and 3, which can be isolated from the leaves of Nelumbo nucifera (Nymphaceae), has been achieved in which the longest linear sequence is only six steps from commercially available benzaldehyde in 28%, 21%, and 20% overall yield, respectively. The key transformations in the synthesis are the radical cyclization of aryl bromide with Bu3SnH and the Pictet-Spengler reaction of N-substituted amine with aldehyde.
