Check Digit Verification of cas no

The CAS Registry Mumber 1224738-22-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,4,7,3 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1224738-22:
(9*1)+(8*2)+(7*2)+(6*4)+(5*7)+(4*3)+(3*8)+(2*2)+(1*2)=140
140 % 10 = 0
So 1224738-22-0 is a valid CAS Registry Number.

Rhodium-catalyzed domino conjugate addition-cyclization reactions for the synthesis of a variety of N- and O-heterocycles: Arylboroxines as effective carbon nucleophiles

Park, Ja Ock,Youn, So Won

supporting information; experimental part, p. 2258 - 2261 (2010/07/17)

Facile and efficient Rh(I)-catalyzed domino conjugate addition-cyclization reactions of olefins bearing two electrophilic sites and a pendant nucleophile with organoboroxines have been developed to afford a variety of N- and O-heterocycles, such as 3,4-dihydroquinolin-2(1H)-ones, 3,4-dihydrocoumarins, and pyrrolidin-2-ones, which constitute important motifs in biologically active natural and synthetic organic compounds.
