Check Digit Verification of cas no

The CAS Registry Mumber 1377322-25-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,7,3,2 and 2 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1377322-25:
(9*1)+(8*3)+(7*7)+(6*7)+(5*3)+(4*2)+(3*2)+(2*2)+(1*5)=162
162 % 10 = 2
So 1377322-25-2 is a valid CAS Registry Number.

N -heterocyclic carbene (NHC)-catalyzed highly diastereo- and enantioselective oxo-Diels-Alder reactions for synthesis of fused pyrano[2,3- b ]indoles

Yang, Limin,Wang, Fei,Chua, Pei Juan,Lv, Yunbo,Zhong, Liang-Jun,Zhong, Guofu

supporting information; experimental part, p. 2894 - 2897 (2012/07/14)

A chiral N-heterocyclic carbene (NHC)-catalyzed Diels-Alder reaction of 2-oxoindolin-3-ylidenes and α-chloroaldehydes was developed for the synthesis of fused pyrano[2,3-b]indoles in good to excellent yields (up to 99%) with high cis-diastereoselectivities (>99:1 dr) and enantioselectivities (up to >99% ee).
