1616108-12-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1616108-12-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,6,1,0 and 8 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1616108-12:
(9*1)+(8*6)+(7*1)+(6*6)+(5*1)+(4*0)+(3*8)+(2*1)+(1*2)=133
133 % 10 = 3
So 1616108-12-3 is a valid CAS Registry Number.

The preparation of novel chiral auxiliaries SAMIQ/RAMIQ and their application in the asymmetric Michael addition
Pan, Xuan,Liu, Zhanzhu
, p. 4602 - 4610 (2014/06/23)
A pair of novel chiral auxiliaries SAMIQ/RAMIQ was synthesized from l- or d-phenylalanine methyl ester hydrochloride over six steps in 45.8% and 44.4% yield, respectively. The SAMIQ-/RAMIQ-hydrazone methodology was applied for the asymmetric Michael addit
