Check Digit Verification of cas no

The CAS Registry Mumber 74050-54-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,0,5 and 0 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 74050-54:
(7*7)+(6*4)+(5*0)+(4*5)+(3*0)+(2*5)+(1*4)=107
107 % 10 = 7
So 74050-54-7 is a valid CAS Registry Number.

Synthesis of β-acetoxy alcohols by PhI(OAc)2-mediated metal-free diastereoselective β-acetoxylation of alcohols

Zhao, Chun-Yang,Li, Liang-Gui,Liu, Qing-Rong,Pan, Cheng-Xue,Su, Gui-Fa,Mo, Dong-Liang

, p. 6795 - 6803 (2016/07/23)

β-Acetoxy alcohols can be synthesized in good yields with excellent diastereoselectivity from tertiary alcohols through PhI(OAc)2-mediated metal-free β-acetoxylation. Mechanistic studies showed that the β-acetoxylation process might undergo dehydration and sequential highly regioselective and diastereoseletive dioxygenation. Gram scale and diverse useful scaffolds could be prepared via this β-acetoxylation process.
