Check Digit Verification of cas no

The CAS Registry Mumber 1203507-22-5 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 2 respectively.
Calculate Digit Verification of CAS Registry Number 1203507-22:
(9*1)+(8*2)+(7*0)+(6*3)+(5*5)+(4*0)+(3*7)+(2*2)+(1*2)=95
95 % 10 = 5
So 1203507-22-5 is a valid CAS Registry Number.

Isothiourea-catalyzed enantioselective carboxy group transfer

Joannesse, Caroline,Johnston, Craig P.,Concellon, Carmen,Simal, Carmen,Philp, Douglas,Smith, Andrew D.

supporting information; experimental part, p. 8914 - 8918 (2010/02/28)

Transferable skills: Enantiomerically pure isothioureas promote the 0-to C-carboxyl group transfer of oxazolyl carbonates with excellent levels of enantiocontrol (see scheme). The origin of the enantioselectivity of this process was probed mechanistically and rationalized computationally.
