671199-53-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 671199-53-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,1,1,9 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 671199-53:
(8*6)+(7*7)+(6*1)+(5*1)+(4*9)+(3*9)+(2*5)+(1*3)=184
184 % 10 = 4
So 671199-53-4 is a valid CAS Registry Number.

Synthesis of (+)-(2R,3S,4R)-2,3,4-trihydroxycyclohexanone from D-glucose
Carvalho, Ivone,De Melo, Eduardo B.
, p. 361 - 365 (2007/10/03)
We have described the synthesis of (+)-(2R,3S,4R)-2,3,4- trihydroxycyclohexanone by the reduction of a keto-conduritol derivative, the latter being prepared in five steps from (-)-(2S,3R,4S,5S)-2,3,4-tribenzyloxy-5- hydroxycyclohexanone, which is in turn
