Check Digit Verification of cas no

The CAS Registry Mumber 110744-50-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,7,4 and 4 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 110744-50:
(8*1)+(7*1)+(6*0)+(5*7)+(4*4)+(3*4)+(2*5)+(1*0)=88
88 % 10 = 8
So 110744-50-8 is a valid CAS Registry Number.

Synthesis of (+)-myrtopsine, (+)-7,8-dimethoxymyrtopsine, and related 2,3-dihydro-3-hydroxy-2-(1-hydroxy-1-methyl-ethyl)benzofuran natural products

Snider, Barry B.,Wu, Xiaoxing

, p. 279 - 294 (2006)

The first syntheses of myrtopsine (8t) and 7,8-dimethoxymyrtopsine (9t) have been carried out by halogen-metal exchange of 3-iodo-4-methoxy-quinolin-2(1H)-ones (15) and (21) with i-PrMgCl followed by addition of 3,3-dimethyloxirane-2-carboxaldehyde (1). A two-step sequence leads selectively to trans-2,3-dihydro-3-hydroxy-2-(1-hydroxy-1-methylethyl)benzofurans (7t), (8t), (9t), (28), and (32) by conversion of a 2-iodophenol or a 3-iodo-4-methoxyquinolin-2(1H)-one to an aryl Grignard reagent and addition of 3-methyl-2-butenal, followed by threo selective epoxidation of the resulting allylic alcohol and cyclization with inversion.
