Check Digit Verification of cas no

The CAS Registry Mumber 1200697-08-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,0,6,9 and 7 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1200697-08:
(9*1)+(8*2)+(7*0)+(6*0)+(5*6)+(4*9)+(3*7)+(2*0)+(1*8)=120
120 % 10 = 0
So 1200697-08-0 is a valid CAS Registry Number.

Iron-Catalyzed Cross-Coupling of Propargyl Ethers with Grignard Reagents for the Synthesis of Functionalized Allenes and Allenols

B?ckvall, Jan-E.,Bermejo-López, Aitor,Posevins, Daniels

supporting information, p. 22178 - 22183 (2021/09/06)

Herein we disclose an iron-catalyzed cross-coupling reaction of propargyl ethers with Grignard reagents. The reaction was demonstrated to be stereospecific and allows for a facile preparation of optically active allenes via efficient chirality transfer. Various tri- and tetrasubstituted fluoroalkyl allenes can be obtained in good to excellent yields. In addition, an iron-catalyzed cross-coupling of Grignard reagents with α-alkynyl oxetanes and tetrahydrofurans is disclosed herein, which constitutes a straightforward approach towards fully substituted β- or γ-allenols, respectively.
