1258867-98-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1258867-98-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,8,8,6 and 7 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1258867-98:
(9*1)+(8*2)+(7*5)+(6*8)+(5*8)+(4*6)+(3*7)+(2*9)+(1*8)=219
219 % 10 = 9
So 1258867-98-9 is a valid CAS Registry Number.

An elimination approach to the synthesis of (+)-Scorodonin

1,2-Elimination of optically-active vinyl sulfoxide-allylic acetates led to corresponding allenynes in excellent yields. When the chirality of the sulfinyl group "matched" that at the allylic position, the chirality at the allylic stereogenic center could be efficiently transferred to the allenic axis.
