Check Digit Verification of cas no

The CAS Registry Mumber 282535-09-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,2,5,3 and 5 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 282535-09:
(8*2)+(7*8)+(6*2)+(5*5)+(4*3)+(3*5)+(2*0)+(1*9)=145
145 % 10 = 5
So 282535-09-5 is a valid CAS Registry Number.

Efficient syntheses-of (-)-shikimate and (-)-quinate 3-phosphate via trans vicinal diol protection with 2,2,3,3-tetramethoxybutane (TMB) of shikimic and quinic acids

Shih, Tzenge-Lien,Wu, Shih-Hsiung

, p. 2957 - 2959 (2000)

(-)-Shikimate 3-phosphate and (-)-quinate 3-phosphate can be synthesized by selective protection of their trans diol functionality using 2,2,3,3- tetramethoxybutane (TMB) using D-(-)-shikimic acid and D-(-)-quinic acid as starting materials. This versatile reagent facilitates the synthesis of these important biological targets in fewer steps than previously reported. By the proper choice of protecting group for C-3 hydroxyl in D-(-)-quinic acid, it can be converted to a key intermediate in the synthesis of (-)-shikimate 3- phosphate.
