Check Digit Verification of cas no

The CAS Registry Mumber 1610691-88-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,0,6,9 and 1 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1610691-88:
(9*1)+(8*6)+(7*1)+(6*0)+(5*6)+(4*9)+(3*1)+(2*8)+(1*8)=157
157 % 10 = 7
So 1610691-88-7 is a valid CAS Registry Number.

A diastereoselective construction of pyrazinoisoquinoline skeletons via tandem cyclization of phenylalanine derivatives: A facile synthesis of optically active pyrazinoisoquinolines

Seki, Maki,Ogiku, Tsuyoshi

, p. 3864 - 3870 (2014/06/09)

A facile and stereocontrolled construction of optically active pyrazinoisoquinoline skeletons based on tandem cyclization of enantiopure phenylalanine derivatives was examined. The reaction provided optically active 6,11b-trans pyrazinoisoquinoline ring systems in excellent diastereoselectivity, and this method was applicable to the cyclization of phenylalanine derivatives with diverse substituents.
