Check Digit Verification of cas no

The CAS Registry Mumber 1268809-70-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,8,8,0 and 9 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1268809-70:
(9*1)+(8*2)+(7*6)+(6*8)+(5*8)+(4*0)+(3*9)+(2*7)+(1*0)=196
196 % 10 = 6
So 1268809-70-6 is a valid CAS Registry Number.

Catalytic asymmetric synthesis of 1,1-disubstituted tetrahydro-β- carbolines by phase-transfer catalyzed alkylations

Shirakawa, Seiji,Liu, Kun,Ito, Hironobu,Maruoka, Keiji

, p. 1515 - 1517 (2011/03/20)

Efficient catalytic asymmetric synthesis of 1,1-disubstituted tetrahydro-β-carbolines has been achieved via asymmetric alkylation of 1-cyanotetrahydro-β-carbolines using a binaphthyl-modified N-spiro-type chiral phase-transfer catalyst. This is a valuable
