Check Digit Verification of cas no

The CAS Registry Mumber 1203507-23-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,3,5,0 and 7 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1203507-23:
(9*1)+(8*2)+(7*0)+(6*3)+(5*5)+(4*0)+(3*7)+(2*2)+(1*3)=96
96 % 10 = 6
So 1203507-23-6 is a valid CAS Registry Number.

Isothiourea-mediated asymmetric O- to C-carboxyl transfer of oxazolyl carbonates: Structure-selectivity profiles and mechanistic studies

Joannesse, Caroline,Johnston, Craig P.,Morrill, Louis C.,Woods, Philip A.,Kieffer, Madeleine,Nigst, Tobias A.,Mayr, Herbert,Lebl, Tomas,Philp, Douglas,Bragg, Ryan A.,Smith, Andrew D.

supporting information; experimental part, p. 2398 - 2408 (2012/03/27)

The structural motif within a series of tetrahydropyrimidine-based isothioureas necessary for generating high asymmetric induction in the asymmetric Steglich rearrangement of oxazolyl carbonates is fully explored, with crossover and dynamic 19F NMR experiments used to develop a mechanistic understanding of this transformation.
