Check Digit Verification of cas no

The CAS Registry Mumber 849796-38-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,9,7,9 and 6 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 849796-38:
(8*8)+(7*4)+(6*9)+(5*7)+(4*9)+(3*6)+(2*3)+(1*8)=249
249 % 10 = 9
So 849796-38-9 is a valid CAS Registry Number.

Asymmetric allylboration of α,β-enals as a surrogate for the enantioselective synthesis of allylic amines and α-amino acids

Ramachandran, P. Veeraraghavan,Burghardt, Thomas E.,Reddy, M. Venkat Ram

, p. 2329 - 2331 (2007/10/03)

(Chemical Equation Presented) Optically pure allylic amines have been synthesized from α,β-unsaturated aldehydes via allylboration with (-)-B-allyldiisopinocampheylborane, followed by Overman rearrangement. By incorporating crotyl and alkoxyallylboration, functionalization at δ-position was readily accomplished. By applying this methodology, the synthesis of several chiral α-amino acids has been achieved.
