Check Digit Verification of cas no

The CAS Registry Mumber 1592250-67-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,9,2,2,5 and 0 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1592250-67:
(9*1)+(8*5)+(7*9)+(6*2)+(5*2)+(4*5)+(3*0)+(2*6)+(1*7)=173
173 % 10 = 3
So 1592250-67-3 is a valid CAS Registry Number.

Regioselective passerini and passerini-knoevenagel reactions with vic-diketo amides

Rossbach, Jan,Harms, Klaus,Koert, Ulrich

, p. 993 - 1006 (2014/03/21)

The Passerini reaction of vic-diketo amides with a variety of isocyanides and carboxylic acids has been examined. α-Acyloxy β-keto carboxamides were formed regioselectively as the major products. For the Passerini reactions with electron-withdrawing-group-substituted acetic acids, a one-pot Passerini-Knoevenagel reaction was accomplished by the addition of triethylamine. vic-Diketo amides react with a variety of isocyanides and carboxylic acids in a regioselective Passerini three-component reaction (P-3CR) to give good to excellent yields of α-acyloxy-β-keto-carboxamides. In the case of Passerini reactions with electron-withdrawing-group-substituted acetic acids, a one-pot Passerini-Knoevenagel reaction was accomplished by the addition of triethylamine. Copyright
