Check Digit Verification of cas no

The CAS Registry Mumber 1569317-73-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,6,9,3,1 and 7 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1569317-73:
(9*1)+(8*5)+(7*6)+(6*9)+(5*3)+(4*1)+(3*7)+(2*7)+(1*3)=202
202 % 10 = 2
So 1569317-73-2 is a valid CAS Registry Number.

An efficient synthesis of novel fused cycloheptatrienes through Mn(II)-mediated formal intermolecular [2 + 2 + 2 + 1] cycloaddition

Shu, Wen-Ming,Ma, Jun-Rui,Yang, Yan,Wu, An-Xin

, p. 1286 - 1289 (2014)

A new method for manganous acetate tetrahydrate mediated formal intermolecular [2 + 2 + 2 + 1] cycloaddition was developed for the synthesis of fused cycloheptatriene derivatives from N-(acylmethyl)pyridinium iodides and naphthoquinone. This method provides an innovative route for the efficient and convenient construction of fused seven-membered carbocycles from simple starting materials.
