116556-78-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 116556-78-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,5,5 and 6 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 116556-78:
(8*1)+(7*1)+(6*6)+(5*5)+(4*5)+(3*6)+(2*7)+(1*8)=136
136 % 10 = 6
So 116556-78-6 is a valid CAS Registry Number.

Benzyl Esters of D- and L-Arabinals as Chiral Synthons in Organic Synthesis
Tolstikov, A. G.,Khakhalina, N. V.,Spirikhin, L. V.
, p. 221 - 222 (2007/10/02)
An acidic opening of the benzyl esters of D and L arabinal (1,5-anhydro-2-deoxy-erythro-pent-1-enitol) catalyzed by mercuric sulfate has been proposed as the key step in the preparation of chiral synthons with selectively substituted hydroxy groups.
