Check Digit Verification of cas no
The CAS Registry Mumber 111821-49-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,8,2 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 111821-49:
(8*1)+(7*1)+(6*1)+(5*8)+(4*2)+(3*1)+(2*4)+(1*9)=89
89 % 10 = 9
So 111821-49-9 is a valid CAS Registry Number.

A high-yield synthesis of 4-borono-DL-phenylalanine
Park, Ki Chul,Yoshino, Kazuo,Tomiyasu, Hiroshi
, p. 2041 - 2044 (1999)
A high-yield synthesis of 4-borono-DL-phenylalanine has been achieved by a route which features a highly diastereoselective formation of the Z-isomer of a boron-containing dehydroamino acid derivative.
