344872-72-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 344872-72-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,4,8,7 and 2 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 344872-72:
(8*3)+(7*4)+(6*4)+(5*8)+(4*7)+(3*2)+(2*7)+(1*2)=166
166 % 10 = 6
So 344872-72-6 is a valid CAS Registry Number.

REDUCTION OF α-PYRONE DERIVATIVES WITH BORANE-METHYLSULFIDE COMPLEX

Shimizu, Takeshi,Hiranuma, Sayoko,Watanabe, Tsumoru

, p. 2445 - 2450 (1993)

Selective reduction of the 5-carbomethoxy- and the 5-carboethoxy-4-hydroxy-2H-pyran-2-one derivatives (5a-11, 19) to yield the 5-hydroxymethyl derivatives (12-18) was accomplished using 1.1 mol equivalent of borane-methyl sulfide complex.Additionally, red
