Check Digit Verification of cas no

The CAS Registry Mumber 89998-57-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,9,9 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 89998-57:
(7*8)+(6*9)+(5*9)+(4*9)+(3*8)+(2*5)+(1*7)=232
232 % 10 = 2
So 89998-57-2 is a valid CAS Registry Number.

Thermal Rearrangement of Vinylallenes: Synthesis of 3-Deoxy-1α-hydroxy-14-epiprevitamin D3

Jeganathan, S.,Johnston, Allen D.,Kuenzel, Elizabeth A.,Norman, Anthony W.,Okamura, Willian H.

, p. 2152 - 2158 (2007/10/02)

The lithium salt of the terminal allene 12a was reacted with keto enol ether 13 to give the vinylallenones 8a(6R) and 9a(6S).On reduction with sodium borohydride, 8a afforded vinylallenols 8b(1R,6R) and 8c(1S,6R); similarly 9a gave 9b(1R,6S) and 9c(1S,6S)
