Check Digit Verification of cas no

The CAS Registry Mumber 109459-35-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,4,5 and 9 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 109459-35:
(8*1)+(7*0)+(6*9)+(5*4)+(4*5)+(3*9)+(2*3)+(1*5)=140
140 % 10 = 0
So 109459-35-0 is a valid CAS Registry Number.

Synthesis of Enantiomerically Pure α-Hydroxyaldehydes from the Corresponding α-Hydroxycarboxylic acids: Novel Substrates for Escherichia coli Transketolase

Humphrey, Andrew J.,Turner, Nicholas J.,McCague, Raymond,Taylor, Stephen J. C.

, p. 2475 - 2476 (2007/10/03)

Enantiomerically pure (R)-α-hydroxyaldehydes (>95percent ee) are prepared from the corresponding α-hydroxyesters by silyl protection, reduction with diisobutylaluminium hydride, and finally deprotection under acidic conditions; subsequent coupling of these aldehydes with lithium hydroxypyruvate, catalysed by Escherichia coli transketolase, leads to novel optically pure triols.
