Check Digit Verification of cas no

The CAS Registry Mumber 1241859-97-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,1,8,5 and 9 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1241859-97:
(9*1)+(8*2)+(7*4)+(6*1)+(5*8)+(4*5)+(3*9)+(2*9)+(1*7)=171
171 % 10 = 1
So 1241859-97-1 is a valid CAS Registry Number.

Transition-metal-catalyzed domino reactions: Efficient one-pot regiospecific synthesis of highly functionalized polysubstituted furans from electron-deficient alkynes and 2-Yn-1-ols

Cao, Hua,Jiang, Huanfeng,Huang, Huawen

experimental part, p. 1019 - 1036 (2011/05/14)

Based on the reactive behavior of different transition-metal catalysts, three methods for the synthesis of highly functionalized polysubstituted furan derivatives are presented: (i) copper(I) iodide catalyzed regiospecific synthesis of furan aldehydes/ketones from alkynols and diethyl but-2-ynedioate under atmospheric pressure; (ii) nano-Cu-catalyzed domino process for the regioselective synthesis of -carbonylfurans from readily accessible starting materials; (iii) silver-catalyzed one-pot cyclization in toluene at 50 C for the synthesis of furan derivatives. It was notably that all the domino reactions were smooth under mild conditions with commercially available catalysts, and afforded highly functionalized furans in moderate to good yields. As we know, furans derivatives are extremely useful organic molecules used as synthetic building blocks for the synthesis of more elaborate heterocyclic compounds. Georg Thieme Verlag Stuttgart.
