Check Digit Verification of cas no

The CAS Registry Mumber 1504566-52-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,0,4,5,6 and 6 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1504566-52:
(9*1)+(8*5)+(7*0)+(6*4)+(5*5)+(4*6)+(3*6)+(2*5)+(1*2)=152
152 % 10 = 2
So 1504566-52-2 is a valid CAS Registry Number.

Ethyl glyoxylate N -tosylhydrazone as sulfonyl-transfer reagent in base-catalyzed sulfa-Michael reactions

Fernandez, Maitane,Uria, Uxue,Orbe, Lucia,Vicario, Jose L.,Reyes, Efraim,Carrillo, Luisa

, p. 441 - 445 (2014)

Ethyl glyoxylate N-tosylhydrazone has been identified as an excellent sulfonyl anion surrogate in the DBU-catalyzed conjugate addition reaction with enones and enals for the synthesis of functionalized sulfones. The reaction proceeds under base-catalyzed conditions and provides a direct access to γ-keto- and γ-hydroxy sulfones in a simple and reliable way through a sulfa-Michael reaction that proceeds with high yield and chemoselectivity.
