Check Digit Verification of cas no

The CAS Registry Mumber 124643-23-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,6,4 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 124643-23:
(8*1)+(7*2)+(6*4)+(5*6)+(4*4)+(3*3)+(2*2)+(1*3)=108
108 % 10 = 8
So 124643-23-8 is a valid CAS Registry Number.

THE REACTION OF INDOLYL GRIGNARD AND RELATED ORGANOMETALLIC REAGENTS WITH 2-PHENYLSULPHONYLBUTA-1,3-DIENE AND 2,3-DIPHENYLSULPHONYLBUTA-1,3-DIENE

Barnwell, Neil,Beddoes, Roy L.,Mitchell, Michael B.,Joule, John A.

, p. 175 - 180 (2007/10/02)

Indolyl Grignard reagents, and some related organometallic species, react with 2,3-diphenylsulfonylbuta-1,3-diene producing RCH2C(SO2Ph)=C=CH2, where R is derived from the organometallic reagent.

FACILE CYCLOADDITION OF 2-PHENYLSULFONYL 1,3-DIENES TO INDOLES

Baeckvall, Jan-E.,Plobeck, Niklas A.,Juntunen, Seppo K.

, p. 2589 - 2592 (2007/10/02)

2-Phenylsulfonyl 1,3-dienes react rapidly with the magnesium salt of indoles to give 3-(phenylsulfonyl)-1,4,4a,9a-tetrahydrocarbazoles via a formal cycloaddition.
