Check Digit Verification of cas no

The CAS Registry Mumber 126971-87-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,9,7 and 1 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 126971-87:
(8*1)+(7*2)+(6*6)+(5*9)+(4*7)+(3*1)+(2*8)+(1*7)=157
157 % 10 = 7
So 126971-87-7 is a valid CAS Registry Number.

Aryl/heteroaryl pentafluorobenzenesulfonates (ArOPFBs): New electrophilic coupling partners for room temperature Suzuki-Miyaura cross-coupling reactions

Joseph, Jayan T.,Sajith, Ayyiliath M.,Ningegowda, Revanna C.,Nagaraj, Archana,Rangappa,Shashikanth, Sheena

supporting information, p. 5106 - 5111 (2015/08/06)

The first cross-coupling reaction between aryl/heteroaryl pentafluorobenzenesulfonates and aryl/heteroaryl boronic acids under mild conditions is described. The successful synthesis of highly ortho substituted biaryls and high chemoselectivity of these bench stable intermediates over tosylates, triflates, mesylates, and chlorides increases its scope as a valuable cross-coupling partner. The generality of this protocol was further extended to other boron containing nucleophiles (boronates, trifluoroborates) and alkyl boronic acids.
