Check Digit Verification of cas no

The CAS Registry Mumber 566930-72-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,6,6,9,3 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 566930-72:
(8*5)+(7*6)+(6*6)+(5*9)+(4*3)+(3*0)+(2*7)+(1*2)=191
191 % 10 = 1
So 566930-72-1 is a valid CAS Registry Number.

Synthesis of α-methyl kainic acid by stereospecific lithiation-dearomatizing cyclization of a chiral benzamide

Clayden, Jonathan,Knowles, Faye E.,Menet, Christel J.

, p. 3397 - 3400 (2007/10/03)

Stereospecific lithiation of N-α-methylbenzyl benzamides gives configurationally stable tertiary benzyllithiums which undergo a stereospecific dearomatizing cyclization with >99% retention of stereochemistry. The products are partially saturated isoindolinones which carry a new fully-substituted stereogenic centre. A ten-step sequence converts one of these products to the α-methyl analogue of kainic acid.
