Check Digit Verification of cas no

The CAS Registry Mumber 124989-33-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,9,8 and 9 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 124989-33:
(8*1)+(7*2)+(6*4)+(5*9)+(4*8)+(3*9)+(2*3)+(1*3)=159
159 % 10 = 9
So 124989-33-9 is a valid CAS Registry Number.

RADICAL CYCLIZATION ONTO 2(5H)-FURANONE AND MALEATE ELECTROPHORES. AN APPROACH TO THE SPIRO- AND LINEAR-FUSED γ-LACTONE RING SYSTEMS FOUND IN THE GINKGOLIDES

Harrison, Timothy,Myers, Peter L.,Pattenden, Gerald

, p. 5247 - 5262 (1989)

Intramolecular radical cyclizations involving α-acetal methyl centres, and 2(5H)-furanone and maleate electrophores, allow the facile synthesis of spiro- and linear-fused γ-lactone ring systems e.g. (5), (6), (7) and (8) present in the 'ginkgolides' viz (1) and (2) produced by the ginko tree Ginkgo biloba.

RADICAL CYCLISATIONS ONTO 2(5H)-FURANONE AND MALEATE ELECTROPHORES LEADING TO SPIRO- AND LINEAR-FUSED γ-LACTONE RING SYSTEMS

Harrison, Timothy,Pattenden, Gerald

, p. 3869 - 3872 (2007/10/02)

Radical cyclisations involving α-acetal methyl centres and 2(5H)-furanone and maleate electrophores allow the facile syntheses of spiro- and linear-fused γ-lactone ring systems e.g. (6), (10), (14), and (19), found in the ginkgolides.
