Check Digit Verification of cas no

The CAS Registry Mumber 1408234-32-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,8,2,3 and 4 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1408234-32:
(9*1)+(8*4)+(7*0)+(6*8)+(5*2)+(4*3)+(3*4)+(2*3)+(1*2)=131
131 % 10 = 1
So 1408234-32-1 is a valid CAS Registry Number.

Concise construction of the tetracyclic core of lycorine-type alkaloids and the formal synthesis of α-lycorane based on asymmetric bifunctional thiourea-catalyzed cascade reaction

Wang, Yao,Luo, Yong-Chun,Zhang, Hong-Bo,Xu, Peng-Fei

, p. 8211 - 8215 (2012)

A concise and stereoselective construction of the tetracyclic core of lycorine-type alkaloids and the formal synthesis of α-lycorane has been achieved. The feature of the current method is the employment of a bifunctional thiourea-catalyzed cascade reaction as a powerful tool to construct the skeleton of the natural product, which is a challenging yet very rarely explored strategy. As a result, the tetracyclic core is efficiently synthesized in just three simple operations involving two consecutive cascade reactions. The Royal Society of Chemistry 2012.
