Check Digit Verification of cas no

The CAS Registry Mumber 20204-08-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,2,0 and 4 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 20204-08:
(7*2)+(6*0)+(5*2)+(4*0)+(3*4)+(2*0)+(1*8)=44
44 % 10 = 4
So 20204-08-4 is a valid CAS Registry Number.

supporting information, p. 4019 - 4023 (2018/10/04)

A novel Pd-catalyzed desulfitative cross-coupling reaction of sodium arylsulfinates with hexaalkyl distannanes is realized, allowing the facile synthesis of functionalized arylstannanes with moderate to excellent yields. The successful implement of gram-scale synthesis and tandem Stille coupling reaction demonstrates the potential applications of this method in organic synthesis.
