Check Digit Verification of cas no

The CAS Registry Mumber 1160293-75-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,0,2,9 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1160293-75:
(9*1)+(8*1)+(7*6)+(6*0)+(5*2)+(4*9)+(3*3)+(2*7)+(1*5)=133
133 % 10 = 3
So 1160293-75-3 is a valid CAS Registry Number.

Enantioselective organocatalytic α-sulfamidation of aldehydes using sulfonyl azides

McGorry, Raymond J.,Allen, Stacey K.,Pitzen, Micha D.,Coombs, Thomas C.

supporting information, p. 4623 - 4627 (2017/11/15)

Enantioselective organocatalytic α-sulfamidation of unbranched aldehydes is described using MacMillan's second-generation imidazolidinone catalyst and o-nitrobenzenesulfonyl azide. The reactions are highly stereoselective (89.9–96.3% ee) with yields up to 71%. A strong correlation between aldehyde structure and product yield was found to exist, with 3-arylpropanals providing the best results. Application to functionalized amino acid synthesis is presented.
