Check Digit Verification of cas no

The CAS Registry Mumber 1220194-01-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,0,1,9 and 4 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1220194-01:
(9*1)+(8*2)+(7*2)+(6*0)+(5*1)+(4*9)+(3*4)+(2*0)+(1*1)=93
93 % 10 = 3
So 1220194-01-3 is a valid CAS Registry Number.

Iminium-allenamine cascade catalysis: One-pot access to chiral 4Hchromenes by a highly enantioselective michael-michael sequence

Zhang, Xinshuai,Zhang, Shilei,Wang, Wei

supporting information; experimental part, p. 1481 - 1484 (2010/05/18)

Chemical Equation Presented Taking the Michael-Michael: A cascade Michael-Michael reaction of aryl or alkyl alkynals, involving an unprecedented iminium - allenamine sequence, is efficiently catalyzed by a chiral diphenylprolinol TBDMS ether, and affords highly functionalized 4H-chromenes in high yields. TBDMS = tert-butyldimethylsilyl.
