Check Digit Verification of cas no

The CAS Registry Mumber 504435-19-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,4,4,3 and 5 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 504435-19:
(8*5)+(7*0)+(6*4)+(5*4)+(4*3)+(3*5)+(2*1)+(1*9)=122
122 % 10 = 2
So 504435-19-2 is a valid CAS Registry Number.

Mechanisms of Sn-to-Zr cyclopentadienyl transfer in the formation of Me2Si-bridged zirconocenes from sila-stanna-tetrahydro-s-indacenes

Hüttenhofer, Mario,Weeber, Armin,Brintzinger, Hans-Herbert

, p. 58 - 62 (2002)

The stereochemistry of Sn-to-Zr transmetalation was studied by reacting ZrCl4 with that isomer of meso-BnMeSi(3-tBu- C5H3)2SnMe2 which has the benzyl group in axial position. Exchange of Sn
