Check Digit Verification of cas no

The CAS Registry Mumber 17313-50-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,3,1 and 3 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 17313-50:
(7*1)+(6*7)+(5*3)+(4*1)+(3*3)+(2*5)+(1*0)=87
87 % 10 = 7
So 17313-50-7 is a valid CAS Registry Number.

Gold-catalyzed homo- And cross-annulation of alkynyl carboxylic acids: a facile access to substituted 4-hydroxy 2: H -pyrones and total synthesis of pseudopyronine A

Choudhary, Shivani,Gayyur,Ghosh, Nayan,Saxena, Anchal

, p. 8716 - 8723 (2020/11/17)

A Au(i)-catalyzed homo- and cross-annulation reaction of alkynyl carboxylic acids offering 3,6-disubstituted 4-hydroxy 2H-pyrones has been demonstrated. The reaction tolerates various substituted alkynyl carboxylic acids and moderate to good yields of α-pyrone scaffolds have been observed. Later, a gram-scale reaction of the acid and the total synthesis of the natural product pseudopyronine A have been carried out successfully.
