Check Digit Verification of cas no

The CAS Registry Mumber 151629-69-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,1,6,2 and 9 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 151629-69:
(8*1)+(7*5)+(6*1)+(5*6)+(4*2)+(3*9)+(2*6)+(1*9)=135
135 % 10 = 5
So 151629-69-5 is a valid CAS Registry Number.

Synthesis of Annulated γ-Lactams via Intramolecular 1,3-Dipolar Cycloadditions of Functionalized N-Allyl α-Diazo Amides

Minami, Toru,Kamitamari, Masashi,Utsunomiya, Tomohisa,Tanaka, Tetsuya,Ichikawa, Junji

, p. 1496 - 1500 (2007/10/02)

N-Allyldiazoacetamides containing a phosphinyl group at the α-position underwent the intramolecular 1, 3-cycloaddition, followed by 1,3-hydrogen shift to afford 6a-diethoxyphosphinyl-3a,4,5,6a-tetrahydropyrrolopyrazol-6(1H)-ones in 74-78percent yields, while the corresponding α-phenylthio amide produced 1-phenylthio-3-azabicyclohexan-2-one in 74percent yield via extrusion of N2 from the intramolecular 1,3-cycloadduct.In the application of these compounds to the conversion of functionality, the former gave a fused tricyclic heterocycle and the latter gave deallylated compounds.
