Check Digit Verification of cas no

The CAS Registry Mumber 1256554-06-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,5,5 and 4 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1256554-06:
(9*1)+(8*2)+(7*5)+(6*6)+(5*5)+(4*5)+(3*4)+(2*0)+(1*6)=159
159 % 10 = 9
So 1256554-06-9 is a valid CAS Registry Number.

Highly enantioselective reduction of β-amino nitroolefins with a simple n-sulfinyl urea as bifunctional catalyst

Liu, Xiang-Wei,Yan, Yan,Wang, Yong-Qiang,Wang, Chao,Sun, Jian

, p. 9204 - 9207 (2012/08/27)

Simple but effective: A structurally simple N-sulfinyl urea was found to be a highly efficient bifunctional catalyst, which allows for the development of a novel pathway for the construction of chiral β-amino nitroalkanes through enantioselective reduction of β-amino nitroolefins by trichlorosilane. High yields and excellent enantioselectivities were obtained for a broad range of β-arylamino nitroolefin substrates (see scheme). Copyright
