Check Digit Verification of cas no

The CAS Registry Mumber 327024-98-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,7,0,2 and 4 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 327024-98:
(8*3)+(7*2)+(6*7)+(5*0)+(4*2)+(3*4)+(2*9)+(1*8)=126
126 % 10 = 6
So 327024-98-6 is a valid CAS Registry Number.

Total synthesis of (-)-colchicine by an oxyallyl [4 + 3] cycloaddition

Lee, Jae Chol,Cha, Jin Kun

, p. 10175 - 10184 (2007/10/03)

An enantioselective synthesis of (-)-colchicine, free from isocolchicine, is delineated and features tandem application of the intramolecular Diels-Alder reaction of acetylene-tethered oxazoles and the [4+3] cycloaddition of oxyallyls. This work underscores the synthetic utility of little explored α-alkoxy substituted oxyallyls. (C) 2000 Elsevier Science Ltd.
