Check Digit Verification of cas no

The CAS Registry Mumber 1708-21-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,0 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1708-21:
(6*1)+(5*7)+(4*0)+(3*8)+(2*2)+(1*1)=70
70 % 10 = 0
So 1708-21-0 is a valid CAS Registry Number.

Umpolung-like Cross-coupling of Tosylhydrazones with 4-Hydroxy-2-pyridones under Palladium Catalysis

Katsina, Tania,Papoulidou, Kyriaki Eleni,Zografos, Alexandros L.

supporting information, p. 8110 - 8115 (2019/10/11)

Tosylhydrazones under palladium catalysis were found to perform cross-coupling reactions with 4-hydroxy-2-pyridones. The umpolung-like reactivity, between the α-carbon of tosylhydrazone and the 3-position of the heterocycle, which is observed in the obtai
