Check Digit Verification of cas no

The CAS Registry Mumber 1428382-57-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,3,8 and 2 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1428382-57:
(9*1)+(8*4)+(7*2)+(6*8)+(5*3)+(4*8)+(3*2)+(2*5)+(1*7)=173
173 % 10 = 3
So 1428382-57-3 is a valid CAS Registry Number.

Synthesis of novel 16-spiro steroids: Spiro-7′-(aryl)tetrahydro-1H- pyrrolo[1,2-c][1,3]thiazolo-trans-androsterone hybrid heterocycles

Kanchithalaivan, Selvaraj,Kumar, Raju Ranjith,Perumal, Subbu

, p. 409 - 417 (2013/04/23)

The 1,3-dipolar cycloaddition of azomethine ylide derived in situ from the reaction of acenaphthylene-1,2-dione and 1,3-thiazolane-4-carboxylic acid to various exocyclic dipolarophiles synthesized from trans-androsterone and trans-dehydroandrosterone afforded a library of novel spiro[5′.2″] acenaphthylene-1″-one-spiro[16.6′]-(7′-aryl) -tetrahydro-1H-pyrrolo [1,2-c][1,3]thiazolo-trans-androsterone/ dehydroandrosterone hybrid heterocycles respectively. These reactions proceeded stereo-specifically affording a single isomer of the 16-spiro steroids in excellent yields.
