1422183-77-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1422183-77-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,2,1,8 and 3 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1422183-77:
(9*1)+(8*4)+(7*2)+(6*2)+(5*1)+(4*8)+(3*3)+(2*7)+(1*7)=134
134 % 10 = 4
So 1422183-77-4 is a valid CAS Registry Number.

The first synthesis of 7-(hydroxymethyl)thiepane-3,4,5-triols from d-(-)-quinic acid
Shih, Tzenge-Lien,Gao, Wei-Lin
, p. 1897 - 1903 (2013/04/10)
Seven thiepanes, the seven-membered-ring thiosugars, were first synthesized in 11-12 steps starting from d-(-)-quinic acid. Each thiepane is unique for its flexible conformation with a hydroxymethyl group at its C7 position. The key step was the deprotect
