38223-57-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 38223-57-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,2,2 and 3 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 38223-57:
(7*3)+(6*8)+(5*2)+(4*2)+(3*3)+(2*5)+(1*7)=113
113 % 10 = 3
So 38223-57-3 is a valid CAS Registry Number.

Direct synthesis of macrodiolides via hafnium(iv) catalysis
De Léséleuc, Mylène,Collins, Shawn K.
supporting information, p. 10471 - 10474 (2015/06/25)
Efficient direct synthesis of macrodiolides via catalysis using Hf(OTf)4 is possible in high yields, forming water as the sole by-product. The first protocol for the direct synthesis of macrodiolides from equimolar mixtures of diols and dicarbo
