Check Digit Verification of cas no

The CAS Registry Mumber 620943-73-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,0,9,4 and 3 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 620943-73:
(8*6)+(7*2)+(6*0)+(5*9)+(4*4)+(3*3)+(2*7)+(1*3)=149
149 % 10 = 9
So 620943-73-9 is a valid CAS Registry Number.

Identification of a novel Michael acceptor group for the reversible addition of oxygen- and sulfur-based nucleophiles. Synthesis and reactivity of the 3-alkylidene-3H-indole 1-oxide function of Avrainvillamide

Myers, Andrew G.,Herzon, Seth B.

, p. 12080 - 12081 (2007/10/03)

The 3-alkylidene-3H-indole 1-oxide functional group found in the naturally occurring alkaloid avrainvillamide has been synthesized by a cross coupling-reductive condensation sequence and found to undergo reversible addition of oxygen- and sulfur-based nucleophiles. Copyright
