Check Digit Verification of cas no
The CAS Registry Mumber 133269-38-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,2,6 and 9 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 133269-38:
(8*1)+(7*3)+(6*3)+(5*2)+(4*6)+(3*9)+(2*3)+(1*8)=122
122 % 10 = 2
So 133269-38-2 is a valid CAS Registry Number.

Selective C-2 opening of 2,3-epoxyesters with HN3-amine system: A viable route to β-hdyroxy-α-amino acids
Saito,Takahashi,Ishikawa,Moriwake
, p. 667 - 670 (2007/10/02)
The combination of hydrogen azide with amines has proven to effect the C-2 opening of 2,3-epoxyester with high regioselectivity uniformly for trans-epoxyesters and depending on their structures for cis-2,3-epoxyesters.
