Check Digit Verification of cas no

The CAS Registry Mumber 1609262-43-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,9,2,6 and 2 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1609262-43:
(9*1)+(8*6)+(7*0)+(6*9)+(5*2)+(4*6)+(3*2)+(2*4)+(1*3)=162
162 % 10 = 2
So 1609262-43-2 is a valid CAS Registry Number.

Novel tartrate-derived guanidine-catalyzed highly enantio- and diastereoselective Michael addition of 3-substituted oxindoles to nitroolefins

Zou, Liwei,Bao, Xiaoze,Ma, Yuanyuan,Song, Yuming,Qu, Jingping,Wang, Baomin

supporting information, p. 5760 - 5762 (2014/05/20)

The Michael addition of 3-substituted oxindoles to nitroolefins was catalyzed by a novel tartrate-derived guanidine in high yield with excellent diastereo- and enantioselectivity. This method showed an extraordinarily broad substrate scope in terms of both reaction partners. the Partner Organisations 2014.
