19982-04-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 19982-04-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,8 and 2 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 19982-04:
(7*1)+(6*9)+(5*9)+(4*8)+(3*2)+(2*0)+(1*4)=148
148 % 10 = 8
So 19982-04-8 is a valid CAS Registry Number.

Colloid and nanosized catalysts in organic synthesis: IX hydrogenation of enamines with hydrogen at atmospheric pressure
Mokhov,Popov,Nebykov
, p. 2073 - 2075 (2015/02/02)
Hydrogenation of enamines with hydrogen at atmospheric pressure was performed using nickel nanoparticles as a catalyst. The reaction may be used to produce tertiary amines under mild conditions using an accessible catalyst.
