Check Digit Verification of cas no

The CAS Registry Mumber 1292281-33-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,2,2,8 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1292281-33:
(9*1)+(8*2)+(7*9)+(6*2)+(5*2)+(4*8)+(3*1)+(2*3)+(1*3)=154
154 % 10 = 4
So 1292281-33-4 is a valid CAS Registry Number.

Functionalization of acetalic C(sp3)-H bonds by scandium(III) triflate-catalyzed intramolecular redox reactions: Tandem 1,4-hydride transfer/1,5-cyclization processes leading to protected 1-indanones

Alajarin, Mateo,Marin-Luna, Marta,Vidala, Angel

, p. 557 - 562 (2011/04/26)

A new C-C bond forming reaction leading to adjacent quaternary carbons is reported. It is a one-pot hydride shift/cyclization process facilitated by the hydricity of the acetalic C-H bonds, with benzylidenemalonate fragments as electrophilic hydride accep
