1186421-97-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1186421-97-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,6,4,2 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1186421-97:
(9*1)+(8*1)+(7*8)+(6*6)+(5*4)+(4*2)+(3*1)+(2*9)+(1*7)=165
165 % 10 = 5
So 1186421-97-5 is a valid CAS Registry Number.

Silylene-mediated ring contraction of homoallylic ethers to form allylic silanes
Bourque, Laura E.,Haile, Pamela A.,Woerpel
, p. 7180 - 7182 (2009)
(Chemical Equation Presented) (-)-Isopulegol derivatives undergo a ring contraction under silylene-mediated conditions to provide cyclopentane products. Silylene transfer to other homoallylic ethers did not provide the ring contraction products. Allylic s
