Check Digit Verification of cas no

The CAS Registry Mumber 191789-23-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,7,8 and 9 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 191789-23:
(8*1)+(7*9)+(6*1)+(5*7)+(4*8)+(3*9)+(2*2)+(1*3)=178
178 % 10 = 8
So 191789-23-8 is a valid CAS Registry Number.

Construction of contiguous chiral tertiary carbon centers by enantioselective Michael reaction of ketone lithium enolates using a chiral amine ligand

Yasuda, Kosuke,Shindo, Mitsum,Koga, Kenji

, p. 3531 - 3534 (1997)

The diastereo- and enantioselective Michael reaction of ketone lithium enolates using a chiral amine ligand (1) was examined. Michael adducts (4) were obtained in excellent chemical yields (95~99%) with high stereoselectivities (syn-4/anti-4: 16/84~1/99;
