Check Digit Verification of cas no

The CAS Registry Mumber 949168-34-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,9,1,6 and 8 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 949168-34:
(8*9)+(7*4)+(6*9)+(5*1)+(4*6)+(3*8)+(2*3)+(1*4)=217
217 % 10 = 7
So 949168-34-7 is a valid CAS Registry Number.

Chiral Magnesium Bisphosphate-Catalyzed Asymmetric Double C(sp3)-H Bond Functionalization Based on Sequential Hydride Shift/Cyclization Process

Mori, Keiji,Isogai, Ryo,Kamei, Yuto,Yamanaka, Masahiro,Akiyama, Takahiko

, p. 6203 - 6207 (2018)

Described herein is a chiral magnesium bisphosphate-catalyzed asymmetric double C(sp3)-H bond functionalization triggered by a sequential hydride shift/cyclization process. This reaction consists of stereoselective domino C(sp3)-H bond functionalization: (1) a highly enantio- and diastereoselective C(sp3)-H bond functionalization by chiral magnesium bisphosphate (first [1,5]-hydride shift), and (2) a highly diastereoselective C(sp3)-H bond functionalization by an achiral catalyst (Yb(OTf)3, second [1,5]-hydride shift).
