Check Digit Verification of cas no

The CAS Registry Mumber 291280-29-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,1,2,8 and 0 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 291280-29:
(8*2)+(7*9)+(6*1)+(5*2)+(4*8)+(3*0)+(2*2)+(1*9)=140
140 % 10 = 0
So 291280-29-0 is a valid CAS Registry Number.

Contribution to the chemistry of boron, 245: Deprotonation of B,B'-Di- tert-butyl-b,b'-difluorenyldiborane(4) and the structure of the Di-tert- butyl-difluorenylidenediborate(2-) anion

Littger, Ralf,Noeth, Heinrich

, p. 1571 - 1579 (2000)

In contrast to the deprotonation of the diorganyl(fluorenyl)boranes tBu2B(fl-H) and Me2B(fl-H), which cannot be achieved uniformly, the deprotonation of B2(tBu)2(fl-H)2 in THF proceeds smoothly to give the anion B2(tBu)2(fl)22-. The isolated salts have been identified as [Na(thf)(n)]2[B2tBu2(fl)2] and [Na(thf)(OEt2){Na(OEt2)2}][B2tBu2(fl)2]. The X-ray structure of the latter compound reveals a longer B-B bond [1.744(9) A] than that in the parent compound B2(tBu2)(fl-H)2 [1.687(7) A]. One sodium center is coordinated to the five-membered ring of one fluorenylidene substituent, while the other is coordinated to three C atoms of one of the six-membered rings. This results in a rather asymmetric structure. Each sodium center is also coordinated by two ether ligands.
