Check Digit Verification of cas no

The CAS Registry Mumber 877037-95-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,7,0,3 and 7 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 877037-95:
(8*8)+(7*7)+(6*7)+(5*0)+(4*3)+(3*7)+(2*9)+(1*5)=211
211 % 10 = 1
So 877037-95-1 is a valid CAS Registry Number.

Stereoselective synthesis of morphine fragments trans- and cis-octahydro-1H-benzo[4,5]furo[3,2-e]isoquinolines

Hsin, Ling-Wei,Chang, Li-Te,Chen, Chien-Wei,Hsu, Chia-Huei,Chen, Hung-Wei

, p. 513 - 520 (2007/10/03)

A stereoselective synthesis of the ACNO partial structures of morphine has been developed. Palladium-catalyzed cyclization of carbamate 2 provided the tetracyclic (ACNO) 3-ethoxycarbonyl-9-methoxy-2,3,5,6,7,7a-hexahydro-1H- benzofuro[3,2-e]isoquinoline (14); while treatment of 5-(2-bromo-6- methoxyphenoxy)-2-methyl-1,2,3,4,5,6,7,8-octahydroisoquinoline (8) under the same reaction condition gave 8a-(2-hydroxy-3-methoxyphenyl)-1,2,3,4,6,7,8,8a- octahydroisoquinoline (11) via an unusual Claisen rearrangement. 9-Methoxy-3-methyl-2,3,5,6,7,7a-hexahydro-1H-benzofuro[3,2-e]isoquinoline (7) was successfully transformed to trans-octahydroisoquinoline 3 and cis-octahydroisoquinoline 4 via catalytical hydrogenation over PtO2 and chemical reduction with acidic NaBH4, respectively.
