Check Digit Verification of cas no

The CAS Registry Mumber 1377181-68-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,7,1,8 and 1 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1377181-68:
(9*1)+(8*3)+(7*7)+(6*7)+(5*1)+(4*8)+(3*1)+(2*6)+(1*8)=184
184 % 10 = 4
So 1377181-68-4 is a valid CAS Registry Number.

Spirocyclohexadienones: XIII.* Reactions of schiff bases with enamines derived from 3,4-Dihydroisoquinoline and with Spiro[naphthalene-1,3'- pyrrol]-4-one

Glushkov,Krainova,Maiorova,Karmanov,Gorbunov,Slepukhin

experimental part, p. 575 - 581 (2012/06/29)

Addition of 1,3,3-trimethyl-3,4-dihydroisoquinolines to N-benzylideneanilines gives substituted N-[2-(3,3-dimethyl-3,4- dihydroisoquinolin-1-yl)-1-phenylethyl]anilines, whereas 2',5',5'-trimethyl-4', 5'-dihydro- 4H-spiro[naphthalene-1,3'-pyrrol]-4-one reacts with N-benzylideneanilines along two pathways involving cyclization to substituted 2,3,3a,4,10,11-hexahydrobenzo[f]pyrrolo[2,3-d]quinolin-5(1H)-ones or elimination of the aniline residue with formation of substituted 5',5'-trimethyl-2-styryl- 4',5'-dihydro-4H-spiro[naphthalene-1,3'-pyrrol]-4-ones.
