Check Digit Verification of cas no

The CAS Registry Mumber 1574615-20-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,7,4,6,1 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1574615-20:
(9*1)+(8*5)+(7*7)+(6*4)+(5*6)+(4*1)+(3*5)+(2*2)+(1*0)=175
175 % 10 = 5
So 1574615-20-5 is a valid CAS Registry Number.

Chiral Bis(imidazolidine)iodobenzene (I-Bidine) Organocatalyst for Thiochromane Synthesis Using an Asymmetric Michael/Henry Reaction

Arai, Takayoshi,Suzuki, Takumi,Inoue, Takahiro,Kuwano, Satoru

supporting information, p. 122 - 127 (2016/12/26)

Bis(imidazolidine)iodobenzene (I-Bidine) was designed as an organocatalyst based on previously reported imidazolidine- or oxazolidine-containing chiral metal catalysts. I-Bidine showed catalytic activity for the Michael/Henry reaction of thiosalicyl aldeh
