Check Digit Verification of cas no

The CAS Registry Mumber 32114-79-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,1,1 and 4 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 32114-79:
(7*3)+(6*2)+(5*1)+(4*1)+(3*4)+(2*7)+(1*9)=77
77 % 10 = 7
So 32114-79-7 is a valid CAS Registry Number.

Efficient cross-coupling of aryl/alkenyl triflates with acyclic secondary alkylboronic acids

Si, Tengda,Li, Bowen,Xiong, Wenrui,Xu, Bin,Tang, Wenjun

supporting information, p. 9903 - 9909 (2017/12/12)

Aryl-secondary alkyl cross-coupling with aryl sulfonate esters as coupling partners remains a significant challenge. Efficient cross-coupling between aryl/alkenyl triflates and acyclic secondary alkylboronic acids is realized for the first time to provide a series of sterically congested acyclic secondary alkyl arenes/olefins in good to excellent yields. The employment of sterically bulky P,PO ligand L1/L2 is crucial for the high yields and selectivities. The method has enabled a concise and 4-step synthesis of a key intermediate of male contraceptive agent and PAF antagonist gossypol.
