Check Digit Verification of cas no

The CAS Registry Mumber 1377806-83-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,7,8,0 and 6 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1377806-83:
(9*1)+(8*3)+(7*7)+(6*7)+(5*8)+(4*0)+(3*6)+(2*8)+(1*3)=201
201 % 10 = 1
So 1377806-83-1 is a valid CAS Registry Number.

Trienamine catalysis with 2,4-dienones: Development and application in asymmetric Diels-Alder reactions

Xiong, Xiao-Feng,Zhou, Quan,Gu, Jing,Dong, Lin,Liu, Tian-Yu,Chen, Ying-Chun

, p. 4401 - 4404 (2012)

A tri-ing reaction: An asymmetric Diels-Alder cycloaddition of δ,δ-disubstituted 2,4-dienones is possible through the trienamine catalysis of cinchona-based primary amines (see scheme). An array of electron-deficient dienophiles, such as N-substituted maleimides and 3-alkenyl oxindoles, were tolerated, and multifunctional cyclohexene derivatives were obtained in excellent stereoselectivity and with high diastereomer ratios.
