Check Digit Verification of cas no

The CAS Registry Mumber 7529-39-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,5,2 and 9 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 7529-39:
(6*7)+(5*5)+(4*2)+(3*9)+(2*3)+(1*9)=117
117 % 10 = 7
So 7529-39-7 is a valid CAS Registry Number.

Reaction between tBuMgCl and SnCl4, illustrating the solvent-dependent predominant formation of Cl(tBu2Sn) nCl (THF, n = 1; Toluene, n = 2; Hexane, n = 3) and the subsequent wavelength-selective photochemical transformation of n = 3 → 2 → 1

Sharma, Hemant K.,Miramontes, Alma,Metta-Magana, Alejandro J.,Pannell, Keith H.

, p. 4501 - 4504 (2011)

The addition of THF solutions of tBuMgCl to SnCl4 in varying solvents (S) results in a dramatic change of the predominant product obtained Cl(tBu2Sn)nCl (n = 1-3). For S = THF the product obtained was tBu2SnCl2, S = toluene, benzene yields Cl(tBu2Sn)2Cl, while for S = hexane the tristannane Cl(tBu2Sn)3Cl was isolated in 45% yield. The last compound is photochemically sensitive when irradiated at 350 nm to form Cl(tBu2Sn)2Cl. Irradiation of this latter material with a 254 nm lamp results in the formation of tBu2SnCl2.
