Check Digit Verification of cas no

The CAS Registry Mumber 384355-71-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,8,4,3,5 and 5 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 384355-71:
(8*3)+(7*8)+(6*4)+(5*3)+(4*5)+(3*5)+(2*7)+(1*1)=169
169 % 10 = 9
So 384355-71-9 is a valid CAS Registry Number.

Bisphosphonate prodrugs. Synthesis and identification of (1-hydroxyethylidene)-1,1-bisphosphonic acid tetraesters by mass spectrometry, NMR spectroscopy and x-ray crystallography

Turhanen, Petri A.,Ahlgren, Markku J.,Jaervinen, Tomi,Vepsaelaeinen, Jouko J.

, p. 115 - 133 (2001)

The preparation and identification of symmetric, H3CC(OH)[P(O)(OR)2]2, where R=Me, Et, Pr1, Ph, and non-symmetric, H3CC(OH)[P(O)(OR1)(OR2)][P(O)(OR3)(O R4)], where R1=Me, R2=R3=R4=Ph; R1=R2=R3=Ph, R4=Me; R1=R3=Me, R2=R4=Ph; R1=R2=Et, Pr1, Ph and R3=R4=Me: tetraester derivatives of etidronate have been studied. Compounds were prepared from HP(O)(OR1)(OR2) and AcP(O)(OR3)(OR4) species under reflux. Mechanism studies have been made using HP(O)(OCD3)(OPh) and AcP(O)(OMe)(OPh) as starting materials. 1H, 13C, 31P NMR data and the MS fragmentation data in the gas phase are reported. The solid-state structures are given for three of the compounds, where R=Et, Ph and R1=R2=Ph, R3=R4=Me.
