Check Digit Verification of cas no
The CAS Registry Mumber 98426-08-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,4,2 and 6 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 98426-08:
(7*9)+(6*8)+(5*4)+(4*2)+(3*6)+(2*0)+(1*8)=165
165 % 10 = 5
So 98426-08-5 is a valid CAS Registry Number.

Palladium and CO: Carbonylation of 1 with [Pd(tfa)2(±)- L1] (tfa=trifluoroacetate) affords the spirofuranone 2 with inversion of the stereochemistry at C17 in 96 % yield. C17-epi-1 also gave the same product 2 with retention of the stereochemistry at C17. Labelling studies show that 13CO was incorporated into the C5′ position of the furanone ring. The first asymmetric version of this new reaction was achieved. Copyright
