1239610-25-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1239610-25-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,9,6,1 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1239610-25:
(9*1)+(8*2)+(7*3)+(6*9)+(5*6)+(4*1)+(3*0)+(2*2)+(1*5)=143
143 % 10 = 3
So 1239610-25-3 is a valid CAS Registry Number.

Urea/transition-metal cooperative catalyst for anti-selective asymmetric nitroaldol reactions
Lang, Kai,Park, Jongwoo,Hong, Sukwon
, p. 1620 - 1624 (2012)
A cooperative catalyst that features urea H-bonding and a cobalt center was developed for anti-selective asymmetric Henry reactions (see scheme). The H-bonds of urea play a crucial role in the improvement in yield (from 30 % to 84 %), enantioselectivity (
