121682-03-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121682-03-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,6,8 and 2 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 121682-03:
(8*1)+(7*2)+(6*1)+(5*6)+(4*8)+(3*2)+(2*0)+(1*3)=99
99 % 10 = 9
So 121682-03-9 is a valid CAS Registry Number.

, p. 3138 - 3141 (2007/10/02)
Reduction of α-phenylthio-β-methoxy ketones 3a-c with Super-hydride gave syn-4a-c, key intermediates to the thermodynamically less stable (Z)-allyl alcohol derivatives 5 and cis-epoxides 6, with high stereoselectivity.
