Check Digit Verification of cas no

The CAS Registry Mumber 1257863-78-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,8,6 and 3 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1257863-78:
(9*1)+(8*2)+(7*5)+(6*7)+(5*8)+(4*6)+(3*3)+(2*7)+(1*8)=197
197 % 10 = 7
So 1257863-78-7 is a valid CAS Registry Number.

Total synthesis of sedum alkaloids via catalyst controlled aza-cope rearrangement and hydroformylation with formaldehyde

Ren, Hong,Wulff, William D.

supporting information, p. 242 - 245 (2013/03/28)

The catalytic asymmetric aminoallylation of chiral aldehydes is developed as a new method for the catalyst controlled synthesis of syn-and anti-1,3-aminoalcohols. This methodology is highlighted in the synthesis of the sedum alkaloids (+)-sedridine and (+)-allosedridine both of which have their final carbon incorporated during closure of the piperidine ring via a hydroformylation with formaldehyde.
