Check Digit Verification of cas no

The CAS Registry Mumber 93323-27-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,3,2 and 3 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 93323-27:
(7*9)+(6*3)+(5*3)+(4*2)+(3*3)+(2*2)+(1*7)=124
124 % 10 = 4
So 93323-27-4 is a valid CAS Registry Number.

Ruthenium-catalyzed formation of pyrazoles or 3-hydroxynitriles from propargyl alcohols and hydrazines

Kaufmann, Julia,J?ckel, Elisabeth,Haak, Edgar

supporting information, p. 91 - 101 (2019/07/09)

Functionalized pyrazoles are generated from secondary propragyl alcohols and hydrazines in a ruthenium-catalyzed cascade process, consisting of redox isomerization, Michael addition, cyclocondensation and dehydrogenation steps. The same bifunctional catalyst mediates the conversion of tertiary propargyl alcohols with hydrazine to 3-hydroxynitriles via anti-Markovnikov hydroamination followed by elimination of ammonia.
