Check Digit Verification of cas no

The CAS Registry Mumber 128237-89-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,2,3 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 128237-89:
(8*1)+(7*2)+(6*8)+(5*2)+(4*3)+(3*7)+(2*8)+(1*9)=138
138 % 10 = 8
So 128237-89-8 is a valid CAS Registry Number.

Nabeshima, Tatsuya,Sakiyama, Akemi,Yagyu, Akiko,Furukawa, Naomichi

, p. 5287 - 5288 (1989)

Sulfur containing biscrown ethers 1red and 1ox have been synthesized, which are interconverted quantitatively by redox reactions between thiol and disulfide.Recognition ability for ammonium salt was found to be dependent upon the redox structures.
