Check Digit Verification of cas no

The CAS Registry Mumber 1396202-52-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,6,2,0 and 2 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1396202-52:
(9*1)+(8*3)+(7*9)+(6*6)+(5*2)+(4*0)+(3*2)+(2*5)+(1*2)=160
160 % 10 = 0
So 1396202-52-0 is a valid CAS Registry Number.

Enantioselective synthesis of 2,6-cis-disubstituted tetrahydropyrans via a tandem catalytic asymmetric hydrogenation/oxa-Michael cyclization: An efficient approach to (-)-centrolobine

Xie, Jian-Hua,Guo, Lu-Chuan,Yang, Xiao-Hui,Wang, Li-Xin,Zhou, Qi-Lin

, p. 4758 - 4761,4 (2012/12/13)

A highly efficient one-pot process via a tandem reaction of catalytic asymmetric hydrogenation and oxa-Michael cyclization for the synthesis of 2,6-cis-disubstituted tetrahydropyrans has been developed (ee up to 99.9%, cis/trans-selectivity up to 99:1). T
