Check Digit Verification of cas no

The CAS Registry Mumber 335627-55-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,5,6,2 and 7 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 335627-55:
(8*3)+(7*3)+(6*5)+(5*6)+(4*2)+(3*7)+(2*5)+(1*5)=149
149 % 10 = 9
So 335627-55-9 is a valid CAS Registry Number.

Versatile synthons for optically pure alpha-amino aldehydes and alpha-amino acids: (+)- and (-)-4,5-dialkoxy-2-oxazolidinones.

Morita,Nagasawa,Yahiro,Matsunaga,Kunieda

, p. 897 - 899 (2007/10/03)

Both enantiomers of trans-5-benzyloxy-4-methoxy- (BMOx) and trans-4,5-dimethoxy-2-oxazolidinones (DMOx), which are readily accessible from simple 2-oxazolone heterocycles, represent good candidates for a new class of chiral synthons for use in the preparation of optically pure alpha-amino aldehydes and alpha-amino acids, respectively.
