161837-04-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 161837-04-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,8,3 and 7 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 161837-04:
(8*1)+(7*6)+(6*1)+(5*8)+(4*3)+(3*7)+(2*0)+(1*4)=133
133 % 10 = 3
So 161837-04-3 is a valid CAS Registry Number.

Kilger, Ralf,Margaretha, Paul
, p. 748 - 753 (1984)
Irradiation (λ = 254 nm) of N-(4,4,6,6-tetramethyl-2-cyclohexen-1-ylidene-1,1,3,3-tetramethylbutylamine (1d) in cyclohexane affords N-(3-cyclohexyl-4,4,6,6-tetramethyl-2-cyclohexen-1-ylidene-1,1,3,3-tetramethylbutylamine (7d), which in turn is photodecomp
