Check Digit Verification of cas no

The CAS Registry Mumber 38940-25-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,9,4 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 38940-25:
(7*3)+(6*8)+(5*9)+(4*4)+(3*0)+(2*2)+(1*5)=139
139 % 10 = 9
So 38940-25-9 is a valid CAS Registry Number.

Synthesis of β-amino ketones by iridium(III)-catalyzed direct-Mannich reaction

Sueki, Shunsuke,Igarashi, Takeyuki,Nakajima, Takayuki,Shimizu, Isao

, p. 682 - 683 (2006)

The direct-Mannich reaction of ketones 1, aldehydes 2, and anilines 3 was studied using catalytic amount of transition-metal complexes. The trivalent iridium complex, [IrCl2(H)(COd)]2, catalyzed the direct-Mannich reaction effectively to give various β-amino kenotes in good yields under mild conditions. Copyright
