1372869-91-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1372869-91-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,2,8,6 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1372869-91:
(9*1)+(8*3)+(7*7)+(6*2)+(5*8)+(4*6)+(3*9)+(2*9)+(1*1)=204
204 % 10 = 4
So 1372869-91-4 is a valid CAS Registry Number.

Two-directional desymmetrization by double 1,4-addition of silicon and boron nucleophiles
Hartmann, Eduard,Oestreich, Martin
, p. 2406 - 2409 (2012/06/29)
The two-directional desymmetrization of prochiral precursors with α,β-unsaturated branches by catalyst-controlled 1,4-addition of silicon and likewise boron nucleophiles allows for a general enantioselective access to syn,anti-triols with 1,n + 1,2n + 1 (
