154230-11-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 154230-11-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,2,3 and 0 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 154230-11:
(8*1)+(7*5)+(6*4)+(5*2)+(4*3)+(3*0)+(2*1)+(1*1)=92
92 % 10 = 2
So 154230-11-2 is a valid CAS Registry Number.

SYNTHESIS AND REACTIONS OF N-SUBSTITUTED PYRAZOLO-3-SULFOLENES
Chou, Ta-shue,Chang, Ruei-Chih
, p. 2839 - 2850 (2007/10/02)
N-Toluenesulfonyl- and N-(anilinocarbonyl)pyrazolo-3-sulfolenes have been prepared from the protected oxotetrahydrothiophenecarbaldehyde (7) via a sequence of hydrazone formation, ketal hydrolysis, cyclization, dehydration, and oxidation reactions.These N
