Check Digit Verification of cas no
The CAS Registry Mumber 127927-48-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,9,2 and 7 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 127927-48:
(8*1)+(7*2)+(6*7)+(5*9)+(4*2)+(3*7)+(2*4)+(1*8)=154
154 % 10 = 4
So 127927-48-4 is a valid CAS Registry Number.

PROTECTIVE GROUP TUNING IN THE STEREOSELECTIVE CONVERSION OF α-AMINO ALDEHYDES INTO AMINOALKYL EPOXIDES
Reetz, M.T.,Binder, J.
, p. 5425 - 5428 (2007/10/02)
Sulfonium and arsonium ylides of the type CH2=S(CH3)2 and CH2=As(Ph)3 react with doubly protected α-amino aldehydes 1 derived from amino acids to form aminoalkyl epoxides 3/4, diastereofacial selectivity ranging between 86:14 and >95:5.
