Check Digit Verification of cas no

The CAS Registry Mumber 1375014-71-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,5,0,1 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1375014-71:
(9*1)+(8*3)+(7*7)+(6*5)+(5*0)+(4*1)+(3*4)+(2*7)+(1*1)=143
143 % 10 = 3
So 1375014-71-3 is a valid CAS Registry Number.

Chiral phosphoric acid-catalyzed enantioselective and diastereoselective spiroketalizations

Sun, Zhankui,Winschel, Grace A.,Borovika, Alina,Nagorny, Pavel

, p. 8074 - 8077 (2012/07/14)

Catalytic enantioselective and diastereoselective spiroketalizations with BINOL-derived chiral phosphoric acids are reported. The chiral catalyst can override the inherent preference for the formation of thermodynamic spiroketals, and highly selective formation of nonthermodynamic spiroketals could be achieved under the reaction conditions.
