Check Digit Verification of cas no

The CAS Registry Mumber 187756-39-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,7,5 and 6 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 187756-39:
(8*1)+(7*8)+(6*7)+(5*7)+(4*5)+(3*6)+(2*3)+(1*9)=194
194 % 10 = 4
So 187756-39-4 is a valid CAS Registry Number.

Remote stereochemical control of both reacting centers in ketyl-olefin radical cyclizations: Involvement of a samarium tridentate ligate

Molander, Gary A.,McWilliams, J. Christopher,Noll, Bruce C.

, p. 1265 - 1276 (1997)

High diastereoselection in a samarium(II) iodide-promoted ketyl-olefin cyclization reaction has been achieved using tartramide-derived keto allylic acetals as chiral auxiliaries. The unique features of the reaction include the fact that remote diastereose
