125991-95-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 125991-95-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,9,9 and 1 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 125991-95:
(8*1)+(7*2)+(6*5)+(5*9)+(4*9)+(3*1)+(2*9)+(1*5)=159
159 % 10 = 9
So 125991-95-9 is a valid CAS Registry Number.

Schwarz, Marian,Kuthan, Josef
, p. 1870 - 1879 (2007/10/02)
A series of photochromic N-methyl derivatives IIIa-IIIh was synthesized by alkylation of 1-sodio-2,4,4,6-tetraphenyl-1,4-dihydropyridine (II) in an inert atmosphere.On the other hand, the starting material II afforded products IVa and IVb in the presence
