Check Digit Verification of cas no

The CAS Registry Mumber 1258059-34-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,8,0,5 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1258059-34:
(9*1)+(8*2)+(7*5)+(6*8)+(5*0)+(4*5)+(3*9)+(2*3)+(1*4)=165
165 % 10 = 5
So 1258059-34-5 is a valid CAS Registry Number.

, p. 1676 - 1679 (2017/02/10)

A metal-free protocol for accessing both α and δ-carboline derivatives, starting from a common indolylchalcone oxime ester precursor is reported. The reaction involves mild conditions and uses a regiodivergent approach. DDQ is used as a switching agent in selectively generating α and δ-carboline derivatives in good to moderate yields.
