Check Digit Verification of cas no

The CAS Registry Mumber 1120310-45-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,2,0,3,1 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1120310-45:
(9*1)+(8*1)+(7*2)+(6*0)+(5*3)+(4*1)+(3*0)+(2*4)+(1*5)=63
63 % 10 = 3
So 1120310-45-3 is a valid CAS Registry Number.

Lewis Acid Mediated [3+2] Coupling of Masked Benzoquinones with Styrenes: Facile Synthesis of 2,3-Dihydrobenzofurans

Sharma, Shivangi,Parumala, Santosh Kumar Reddy,Peddinti, Rama Krishna

supporting information, p. 239 - 244 (2017/01/25)

We have developed an efficient, simple, mild, and rapid method for the construction of dihydrobenzofuran derivatives by the [3+2] coupling of masked o-benzoquinones with styrene derivatives triggered by boron trifluoride diethyl etherate. This new [3+2] coupling protocol proceeds smoothly to afford dihydrobenzofuran derivatives in good to high yields within one minute. The method was extended to cycloaddition of p-benzoquinone monoketal with styrenes.

Diels-Alder reactions of 4-halo masked o-benzoquinones. Experimental and theoretical investigations

Surasani, Seshi Reddy,Parumala, Santosh Kumar Reddy,Peddinti, Rama Krishna

, p. 5656 - 5668 (2014/07/22)

The studies on [4 + 2] cycloaddition of 4-halo derivatives of 6,6-dimethoxycyclohexa-2,4-dienones known as orthoquinone monoketals/masked o-benzoquinones are described. The 4-fluoro, 4-chloro- and 4-iodo-masked o-benzoquinones were stable enough for their
