Check Digit Verification of cas no

The CAS Registry Mumber 491589-49-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,1,5,8 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 491589-49:
(8*4)+(7*9)+(6*1)+(5*5)+(4*8)+(3*9)+(2*4)+(1*9)=202
202 % 10 = 2
So 491589-49-2 is a valid CAS Registry Number.

, p. 6145 - 6148 (2007/10/03)

Chx2BCl-mediated syn-aldol reaction of the α-OTBS lactate-derived ketone 1 followed by in situ reduction of the resulting boron aldolate with LiBH4 lead to complete stereoselectivity for the boronates 2 in 80-95% yields. Then, a very
