Check Digit Verification of cas no

The CAS Registry Mumber 165403-42-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,5,4,0 and 3 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 165403-42:
(8*1)+(7*6)+(6*5)+(5*4)+(4*0)+(3*3)+(2*4)+(1*2)=119
119 % 10 = 9
So 165403-42-9 is a valid CAS Registry Number.

Suppression of the Mattox Rearrangement of 16α-Cyanoprednisolones in Acid: Synthesis of Methyl 16α-Prednisolonecarboxylates

Yuo, Zhengqing,Khalil, Mounir A.,Ko, Dong-Hoon,Lee, Henry J.

, p. 3303 - 3306 (1995)

Prednisolone derivatives with a 16α-methyl carboxylate group were synthesized by a novel procedure of 1,3-dipole addition of fulminic acid to 21-acetyloxy-11β-hydroxy-3,20-dioxo-1,4,16-pregnatriene, followed by base-catalyzed ring opening of the resulting
