Check Digit Verification of cas no

The CAS Registry Mumber 130612-70-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,6,1 and 2 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 130612-70:
(8*1)+(7*3)+(6*0)+(5*6)+(4*1)+(3*2)+(2*7)+(1*0)=83
83 % 10 = 3
So 130612-70-3 is a valid CAS Registry Number.

Efficient Degradation of FK-506 to a Versatile Synthetic Intermediate

Askin, D.,Joe, Daisy,Reamer, R. A.,Volante, R. P.,Shinkai, I.

, p. 5451 - 5454 (2007/10/02)

An 11-step degradation of natural FK-506 (1) to selectively protected C10-C34 synthetic intermediate 2 has been accomplished in 14percent overall yield.The key steps include; (a) lead tetracetate mediated C9-C10 bond cleavage of 24,32-bis(triisopropylsilyl)-FK-506 (3), (b) simultaneous C10 ester, C22 ketone reduction/C26 oxygen deacylation, and (c) selective bis(triethylsilylation) of the resulting triols 7a,b.The degradate 2 is ready for reacylation at the C26 hydroxyl terminus; hydrolysis of the dimethyl acetal moiety then provides an aldehyde ready for homologation at the C10 terminus.
