Check Digit Verification of cas no

The CAS Registry Mumber 1333313-99-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,3,3,1 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1333313-99:
(9*1)+(8*3)+(7*3)+(6*3)+(5*3)+(4*1)+(3*3)+(2*9)+(1*9)=127
127 % 10 = 7
So 1333313-99-7 is a valid CAS Registry Number.

Diterpenoid alkaloid lappaconine derivative catalyzed asymmetric α-hydroxylation of β-dicarbonyl compounds with hydrogen peroxide

Li, Zhi,Lian, Mingming,Yang, Fan,Meng, Qingwei,Gao, Zhanxian

, p. 3491 - 3495 (2014)

A new framework derived from the commercially available diterpenoid alkaloid lappaconitine was evaluated as a Bronsted base catalyst for the enantioselective α-hydroxylation of β-dicarbonyl compounds by using 30% hydrogen peroxide as a green and highly practical source of oxygen. This protocol allows convenient access to the corresponding α-hydroxy-β- oxo esters, α-hydroxy-β-oxo amides and (-)-kjellmanianone with up to 98% yield and 92% ee. Copyright
