Check Digit Verification of cas no

The CAS Registry Mumber 1599432-51-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,9,9,4,3 and 2 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1599432-51:
(9*1)+(8*5)+(7*9)+(6*9)+(5*4)+(4*3)+(3*2)+(2*5)+(1*1)=215
215 % 10 = 5
So 1599432-51-5 is a valid CAS Registry Number.

A one-pot allylation-hydrostannation sequence with recycling of the intermediate tin waste

Ghosh, Banibrata,Amado-Sierra, Maria Del Rosario I.,Holmes, Daniel,Maleczka, Robert E.

supporting information, p. 2318 - 2321 (2014/05/20)

A one-pot allylation and hydrostannation of alkynals where the tin byproduct formed in the first step of the reaction is recycled and used in the second step of the sequence is presented. Specifically, a BF3· OEt2-promoted allylstannation of the aldehyde moiety in the alkynal is followed by the introduction of polymethylhydrosiloxane (PMHS) and catalytic B(C6F5)3, which convert the tin byproduct of the allylation into Bu3SnH, which then hydrostannates the alkyne in the molecule. 119Sn and 11B NMR data suggest an organotin fluoride species is formed during the allylation step and involved in the tin recycling step.
