Check Digit Verification of cas no

The CAS Registry Mumber 1131881-00-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,1,8,8 and 1 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1131881-00:
(9*1)+(8*1)+(7*3)+(6*1)+(5*8)+(4*8)+(3*1)+(2*0)+(1*0)=119
119 % 10 = 9
So 1131881-00-9 is a valid CAS Registry Number.

An efficient synthesis of 2,5-dihydrofuran-fused bicyclic skeletons via the pd(II)-catalyzed tandem-cyclization reaction of 1,ω-bisallenols

Deng, Youqian,Shi, Yunlong,Ma, Shengming

supporting information; experimental part, p. 1205 - 1208 (2009/08/07)

A palladium(II)-catalyzed tandem double-cyclization reaction of 1,u-bisallenols was developed to form 2,5-dihydrofuran-fused bicyclic skeletons. With "unsymmetric" substrates, the reaction may also be realized with one hydroxyl group being protected as th
